任何人都可以告诉我如何在按下按钮时将特定文本视图中存在的文本复制到剪贴板吗？
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainpage);
textView = (TextView) findViewById(R.id.textview);
copyText = (Button) findViewById(R.id.bCopy);
copyText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
String getstring = textView.getText().toString();
// Help to continue :)
}
});
}
我想在按下按钮
bCopy这里复制文本到剪贴板的方法：
private void setClipboard(Context context, String text) {
if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB) {
android.text.ClipboardManager clipboard = (android.text.ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
clipboard.setText(text);
} else {
android.content.ClipboardManager clipboard = (android.content.ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData.newPlainText("Copied Text", text);
clipboard.setPrimaryClip(clip);
}
}
此方法适用于所有 Android 设备。
作为一个方便的 kotlin 扩展：
fun Context.copyToClipboard(text: CharSequence){
val clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
val clip = ClipData.newPlainText("label",text)
clipboard.setPrimaryClip(clip)
}
更新：
如果您使用 ContextCompat，您应该使用：
ContextCompat.getSystemService(this, ClipboardManager::class.java)

对于 Jetpack Compose
val localClipboardManager = LocalClipboardManager.current
localClipboardManager.setText(AnnotatedString("Your text here"))
就用这个吧。它仅适用于 android api >= 11，在此之前您必须使用 ClipData。
ClipboardManager _clipboard = (ClipboardManager) _activity.getSystemService(Context.CLIPBOARD_SERVICE);
_clipboard.setText(YOUR TEXT);
希望对你有帮助:)
[2015 年 3 月 19 日更新] 就像 Ujjwal Singh 所说，方法
setText这可以在 Kotlin 中完成，如下所示：
var clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
var clip = ClipData.newPlainText("label", file.readText())
clipboard.setPrimaryClip = clip
其中
file.readText()fun Context.copyToClipboard(text: CharSequence){
val clipboard = ContextCompat.getSystemService(this,ClipboardManager::class.java)
clipboard?.setPrimaryClip(ClipData.newPlainText("",text))
}
使用此代码
private ClipboardManager myClipboard;
private ClipData myClip;
TextView textView;
Button copyText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainpage);
textView = (TextView) findViewById(R.id.textview);
copyText = (Button) findViewById(R.id.bCopy);
myClipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
copyText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String text = textView.getText().toString();
myClip = ClipData.newPlainText("text", text);
myClipboard.setPrimaryClip(myClip);
Toast.makeText(getApplicationContext(), "Text Copied",
Toast.LENGTH_SHORT).show();
}
});
}
使用此功能复制到剪贴板
public void copyToClipboard(String copyText) {
int sdk = android.os.Build.VERSION.SDK_INT;
if (sdk < android.os.Build.VERSION_CODES.HONEYCOMB) {
android.text.ClipboardManager clipboard = (android.text.ClipboardManager)
getSystemService(Context.CLIPBOARD_SERVICE);
clipboard.setText(copyText);
} else {
android.content.ClipboardManager clipboard = (android.content.ClipboardManager)
getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData
.newPlainText("Your OTP", copyText);
clipboard.setPrimaryClip(clip);
}
Toast toast = Toast.makeText(getApplicationContext(),
"Your OTP is copied", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.BOTTOM | Gravity.RIGHT, 50, 50);
toast.show();
//displayAlert("Your OTP is copied");
}
@SuppressLint({ "NewApi", "NewApi", "NewApi", "NewApi" })
@SuppressWarnings("deprecation")
@TargetApi(11)
public void onClickCopy(View v) { // User-defined onClick Listener
int sdk_Version = android.os.Build.VERSION.SDK_INT;
if(sdk_Version < android.os.Build.VERSION_CODES.HONEYCOMB) {
android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
clipboard.setText(textView.getText().toString()); // Assuming that you are copying the text from a TextView
Toast.makeText(getApplicationContext(), "Copied to Clipboard!", Toast.LENGTH_SHORT).show();
}
else {
android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData.newPlainText("Text Label", textView.getText().toString());
clipboard.setPrimaryClip(clip);
Toast.makeText(getApplicationContext(), "Copied to Clipboard!", Toast.LENGTH_SHORT).show();
}
}
如果你想从edittext复制文本，那么首先创建Edittext
EditText mResultEt = findViewById(R.id.resultEt);
然后创建一个按钮，单击后我们可以复制这些文本
ImageButton copyClipBoard = findViewById(R.id.btn_copy);
然后使用按钮的监听器
Java
copyClipBoard.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
ClipboardManager clipboardManager = (ClipboardManager)
getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clipData = ClipData.newPlainText("nonsense_data",
mResultEt.getText().toString());
clipboardManager.setPrimaryClip(clipData);
Toast.makeText(MainActivity.this, R.string.copied_to_clipboard, Toast.LENGTH_SHORT).show();
}
});
科特林
btn1.setOnClickListener{
val clipboardManager = getSystemService(CLIPBOARD_SERVICE) as ClipboardManager
val clipData = ClipData.newPlainText(
"nonsense_data",
content_et.getText().toString()
)
clipboardManager.setPrimaryClip(clipData)
Toast.makeText(this@MainActivity, R.string.copied_to_clipboard, Toast.LENGTH_SHORT).show()
}
并确保导入此
import android.content.ClipboardManager;
不要导入这个
android.text.ClipboardManager
使用这个方法：
ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText(label, text);
clipboard.setPrimaryClip(clip);
在setPrimaryClip的地方我们还可以使用以下方法：
void clearPrimaryClip()
清除剪贴板上的所有当前主剪辑。
ClipData getPrimaryClip()
返回剪贴板上当前的主剪辑。
ClipDescription getPrimaryClipDescription()
返回剪贴板上当前主剪辑的描述，但不返回其数据的副本。
CharSequence getText()
此方法已被弃用。请改用 getPrimaryClip()。这会检索主剪辑并尝试将其强制为字符串。
boolean hasPrimaryClip()
如果剪贴板上当前存在主剪辑，则返回 true。
使用 Java 简单易用的 Android。
copytext.setOnClickListener(v -> {
ClipboardManager myClipboard;
myClipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);
ClipData myClip;
String Text = "Hello World!";
myClip = ClipData.newPlainText("text", Text);
myClipboard.setPrimaryClip(myClip);
Toast.makeText(this, "Copy", Toast.LENGTH_SHORT).show();
});
ClipboardManager clipboard = (ClipboardManager) mContext.getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText(label, text);
clipboard.setPrimaryClip(clip);
使用 Jetpack Compose，这真的很简单：
AmbientClipboardManager.current.setText(AnnotatedString("Copied Text"))
Kotlin 中最简单的代码 -
val myClipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager val myClip: ClipData = ClipData.newPlainText("Label", "text") myClipboard.setPrimaryClip(myClip)
注意：确保您导入了 android.content.ClipboardManager 而不是 android.text.ClipboardManager。后者已被弃用。
import android.content.ClipData
import android.content.ClipboardManager
import android.content.Context
val clipboardManager = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
clipboardManager.setPrimaryClip(ClipData.newPlainText("text","this is copied...paste it" ))
int sdk = android.os.Build.VERSION.SDK_INT;
if (sdk < android.os.Build.VERSION_CODES.HONEYCOMB) {
android.text.ClipboardManager clipboard = (android.text.ClipboardManager) DetailView.this
.getSystemService(Context.CLIPBOARD_SERVICE);
clipboard.setText("" + yourMessage.toString());
Toast.makeText(AppCstVar.getAppContext(),
"" + getResources().getString(R.string.txt_copiedtoclipboard),
Toast.LENGTH_SHORT).show();
} else {
android.content.ClipboardManager clipboard = (android.content.ClipboardManager) DetailView.this
.getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData
.newPlainText("message", "" + yourMessage.toString());
clipboard.setPrimaryClip(clip);
Toast.makeText(AppCstVar.getAppContext(),
"" + getResources().getString(R.string.txt_copiedtoclipboard),
Toast.LENGTH_SHORT).show();
}
String stringYouExtracted = referraltxt.getText().toString();
android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getActivity().getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clip = android.content.ClipData.newPlainText("Copied Text", stringYouExtracted);
clipboard.setPrimaryClip(clip);
Toast.makeText(getActivity(), "Copy coupon code copied to clickboard!", Toast.LENGTH_SHORT).show();
用于将文本复制到剪贴板的简单 Kotlin 扩展功能
fun Context.copyToClipboard(clipLabel: String, text: CharSequence){
val clipboard = ContextCompat.getSystemService(this, ClipboardManager::class.java)
clipboard?.setPrimaryClip(ClipData.newPlainText(clipLabel, text))
toast("Copied $clipLabel")
}
尝试以下代码。它将支持最新的API：
ClipboardManager clipboard = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
if (clipboard.hasPrimaryClip()) {
android.content.ClipDescription description = clipboard.getPrimaryClipDescription();
android.content.ClipData data = clipboard.getPrimaryClip();
if (data != null && description != null && description.hasMimeType(ClipDescription.MIMETYPE_TEXT_PLAIN))
{
String url= (String) clipboard.getText();
searchText.setText(url);
System.out.println("data="+data+"description="+description+"url="+url);
}}
将此方法放在 Util 类中的某个位置。此方法在 textview 上附加单击侦听器，以便在单击该 textView 时将 textView 的内容复制到 ClipText
/**
* Param: cliplabel, textview, context
*/
fun attachClickToCopyText(textView: TextView?, clipLabel: String, context: Context?) {
if (textView != null && null != context) {
textView.setOnClickListener {
val clipboard = context.getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
val clip = ClipData.newPlainText(clipLabel, textView!!.text)
clipboard.primaryClip = clip
Snackbar.make(textView,
"Copied $clipLabel", Snackbar.LENGTH_LONG).show()
}
}
}
您可以在 onclick 按钮事件时执行此复制到剪贴板功能。因此，请将这些代码行放入按钮 onClickListerner
android.content.ClipboardManager clipboardManager = (android.content.ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
android.content.ClipData clipData = android.content.ClipData.newPlainText("Text Label", ViewPass.getText().toString());
clipboardManager.setPrimaryClip(clipData);
Toast.makeText(getApplicationContext(),"Copied from Clipboard!",Toast.LENGTH_SHORT).show();
在 Kotlin 我有一个扩展
fun Context.copyToClipboard(text: String) {
val clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
val clip =
ClipData.newPlainText(getString(R.string.copy_clipboard_label, getString(R.string.app_name)),text)
clipboard.setPrimaryClip(clip)
}
复制 Android 中的任何文本：
TextView text = findViewById(R.id.text_id);
ImageView icons = findViewById(R.id.copy_icon);
icons.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ClipboardManager clipboardManager = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clipData = ClipData.newPlainText("text whatever you want", text.getText().toString());
clipboardManager.setPrimaryClip(clipData);
Toast.makeText(context, "Text Copied", Toast.LENGTH_SHORT).show();
}
});
要搜索剪贴板列表，首先获取剪贴板对象，如下所示：
private val clipboard = context.getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
然后通过此功能检查剪贴板中是否有数据：
fun isClipboardContainsData() : Boolean{
return when{
!clipboard.hasPrimaryClip() -> false
else -> true
}
}
然后使用此函数来浏览剪贴板对象，如下所示：
fun searchClipboard() : ClipData.Item? {
return if (isClipboardContainsData()){
val items = clipboard.primaryClip
val clipboardSize = items?.itemCount ?: 0
for (i in 0..clipboardSize) {
val item = items?.getItemAt(i)
return if (item != null){
return item
}else
null
}
return null
}else
null
}
在这里您可以看到 searchClipboard Item 将返回 ClipData.Item 类型的项目，剪贴板包含 ClipData.Item 的列表，如果您完成剪贴板的实现，您将发现关于 ClipData.Item 的内容：
public static class Item {
final CharSequence mText;
final String mHtmlText;
final Intent mIntent;
@UnsupportedAppUsage(maxTargetSdk = Build.VERSION_CODES.P, trackingBug = 115609023)
Uri mUri;
}
因此您可以在剪贴板项目中保存的内容可以是以下类型：
如果你想缩短时间，请使用：
ClipData clip = ClipData.newPlainText(label, text);
((ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE)).setPrimaryClip(clip);
==> 单击“查看”即可复制内容太容易了。
-> 将文本存储到字符串变量中。
-> 使 ClipboardManager 成为变量
-> 将 ClipData 设为变量
-> 必须从包中导入为“ android.content。”
-> 将剪辑设置到剪贴板.setPrimaryclick。
-> 完成。
例如。
import android.content.ClipboardManager;
import android.content.ClipData;
stringNodetxt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String stringNodeCopied= stringNodetxt.getText().toString();
ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = android.content.ClipData.newPlainText("Copied", stringNodeCopied);
clipboard.setPrimaryClip(clip);
Toast.makeText(getBaseContext(), "copied to clipboard!", Toast.LENGTH_SHORT).show();
}
});
对于科特林 只需在您的按钮中输入此代码即可。此代码适用于 Fragment 类。
var myClipboard = getSystemService(requireContext(), ClipboardManager::class.java) as ClipboardManager
val copyText = quotes//quotes is actual text(I want to copy) that is assign in copyText.
val clip = ClipData.newPlainText("Copied",copyText)
myClipboard.setPrimaryClip(clip)
Toast.makeText(requireActivity(), "Copied", Toast.LENGTH_SHORT).show()
