我创建拖放文本视图，我需要这个文本视图也可以点击。我的代码，按照以下：
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/bg_grey"
android:orientation="vertical" >
<GridView
android:id="@+id/gridview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:background="@color/bg_grey"
android:clickable="true"
android:columnWidth="100dp"
android:gravity="center"
android:horizontalSpacing="10dp"
android:numColumns="2"
android:stretchMode="columnWidth"
android:verticalSpacing="10dp" />
<TextView
android:id="@+id/drag_drop_button"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_marginLeft="255dp"
android:layout_marginTop="155dp"
android:background="@drawable/circle_button"
android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:gravity="center"
android:text="@string/brand"
android:textColor="@color/sign_blue"
android:textSize="15sp"
android:textStyle="bold" />
</FrameLayout>
class ButtonDragListener implements OnDragListener {
Drawable normalShape = getResources().getDrawable(
R.drawable.circle_button);
@Override
public boolean onDrag(View v, DragEvent event) {
int action = event.getAction();
switch (event.getAction()) {
case DragEvent.ACTION_DRAG_STARTED:
// do nothing
break;
case DragEvent.ACTION_DRAG_ENTERED:
// do nothing
break;
case DragEvent.ACTION_DRAG_EXITED:
// do nothing
break;
case DragEvent.ACTION_DROP:
// Dropped, reassign View to ViewGroup
View view = (View) event.getLocalState();
view.setX(event.getX());
view.setY(event.getY());
ViewGroup owner = (ViewGroup) view.getParent();
owner.removeView(view);
FrameLayout container = (FrameLayout) v;
container.addView(view);
view.setVisibility(View.VISIBLE);
break;
case DragEvent.ACTION_DRAG_ENDED:
// do nothing
break;
default:
break;
}
return true;
}
}
private final class ButtonTouchListener implements OnTouchListener {
private static final int MAX_CLICK_DURATION = 200;
private long startClickTime;
public boolean onTouch(View view, MotionEvent motionEvent) {
if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
startClickTime = Calendar.getInstance().getTimeInMillis();
ClipData data = ClipData.newPlainText("", "");
DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(
view);
view.startDrag(data, shadowBuilder, view, 0);
view.setVisibility(View.VISIBLE);
} else if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
long clickDuration = Calendar.getInstance().getTimeInMillis()
- startClickTime;
if (clickDuration < MAX_CLICK_DURATION){
view.performClick();
}
}
return true;
}
}
private final class ButtonOnClickListener implements OnClickListener {
@Override
public void onClick(View v) {
Log.e(TAG, "ALOHAAAAA");
}
}
TextView dragDrop = (TextView) view.findViewById(R.id.drag_drop_button);
dragDrop.setAlpha(0.7f);
dragDrop.setOnClickListener(new ButtonOnClickListener());
dragDrop.setOnTouchListener(new ButtonTouchListener());
frameLayout = (FrameLayout) view.findViewById(R.id.root);
frameLayout.setOnDragListener(new ButtonDragListener());
但是MotionEvent.ACTION_UP永远不会被调用，我也想移动view.performClick()内MotionEvent_ACTION_DOWN，点击听众打电话罚款，但每当我拖动文本查看点击听者也运行。我也有setOnTouchListener和setOnClickListener直接从TextView的，但结果是一样的。
我需要在这里是平滑拖拽和点击也功能。请告知我在做什么错在这里。谢谢你，真的很感激任何一种帮助。
我有你，你的解决方案不是很帮助我同样的问题，所以我想出了这个解决方案，它基于以前的解决方案。
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (Math.abs(event.getX() - mX) < MAX_X_MOVE || Math.abs(event.getY() - mY) < MAX_Y_MOVE) {
v.performClick();
} else {
ClipData clipData = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v);
v.startDrag(clipData, shadowBuilder, v, 0);
v.setVisibility(View.INVISIBLE);
mX = event.getX();
mY = event.getY();
}
return true;
}
return false;
}
这是一种地方虽然有提供解决方案的问题，但也必须考虑这些解决方案将如何满足您的需求。对于我来说，我使用了上述观点，并与自己的解决方案，适合我的需求上来。
/**
* Max value of X to move before we declare that we are going to do
* drag.
*/
private static final float MAX_X_MOVE = 120;
/**
* Max value of Y to move before we declare that we are going to do
* drag.
*/
private static final float MAX_Y_MOVE = 120;
private final static int NONE = 0;
private final static int DRAG = 1;
private int m_mode = NONE;
icon.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
final int action = event.getAction();
switch (action){
case MotionEvent.ACTION_DOWN:
m_mode = NONE;
break;
case MotionEvent.ACTION_MOVE:
if (Math.abs(event.getX()) > MAX_X_MOVE ||
Math.abs(event.getY()) > MAX_Y_MOVE) {
m_mode = DRAG;
_startDragOnFling();
}
break;
case MotionEvent.ACTION_UP:
if(m_mode == DRAG){
break;
}
v.performClick();
break;
}
return true;
}
});
我有我自己的问题的解决方案，我修改了我的课ButtonTouchListener按如下：
private final class ButtonTouchListener implements OnTouchListener {
private static final float MAX_X_MOVE = 70;
private static final float MAX_Y_MOVE = 70;
public boolean onTouch(View view, MotionEvent motionEvent) {
if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
ClipData data = ClipData.newPlainText("", "");
DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(
view);
view.startDrag(data, shadowBuilder, view, 0);
view.setVisibility(View.VISIBLE);
float offset_x = motionEvent.getX();
float offset_y = motionEvent.getY();
Log.d(TAG,"OFFSET X = "+offset_x);
Log.d(TAG,"OFFSET Y = "+offset_y);
if (offset_x < MAX_X_MOVE && offset_y < MAX_Y_MOVE) {
Log.d(TAG,"Here we go");
view.performClick();
}
return true;
} else {
return false;
}
}
}
请注意，我越来越指针x和y的事件，这帮助我指示的TextView是否移动太远，如果它走得比MAX_X_MOVE和MAX_Y_MOVE会被认为是一个阻力运动。也许这可以帮助别人谁遇到同样的问题。任何更好的解决方案，请欢迎:)
它已经发布了阻力监听器，你可以写的TextView setonClickListener方法..
链接在这里..
How to drag the TextView to the correct target other TextView
对于的onClick ..
textView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// your code
}
});
它只是一个想法，设置的onClick在XML TextView的，并调用的onClick方法为好。
android:onClick="onClickTextView"
public void onClickTextView()
{
// your actions
}
试试这个，只是一个想法。你希望工作。
TextView dragDrop = (TextView) view.findViewById(R.id.drag_drop_button);
dragDrop.setAlpha(0.7f);
dragDrop.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
});
在我的应用程序，一系列按钮可以点击或拖动。要做到这一点我有
这是我的实现：
@Override
public void onClick(View v) { }
class ScDragListenerForButton implements OnDragListener {
@Override
public boolean onDrag(View v, DragEvent event) {
return true;
}
}
ScDragListenerForButton mDragListenerForButton = new ScDragListenerForButton();
View.OnLongClickListener onLongClickListener = new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
Button b = (Button) v;
ClipData.Item item = new ClipData.Item(b.getText());
String[] mimeTypes = {ClipDescription.MIMETYPE_TEXT_PLAIN};
ClipData dragData = new ClipData(b.getText(), mimeTypes, item);
View.DragShadowBuilder myShadow = new View.DragShadowBuilder(v);
if (Build.VERSION.SDK_INT < VERSION_CODES.N) {
v.startDrag(dragData, myShadow, null, 0);
} else {
v.startDragAndDrop(dragData, myShadow, null, 0);
}
return true;
}
};
button1.setOnLongClickListener(onLongClickListener);
button1.setOnDragListener(mDragListenerForButton);
尝试这个：
public class MainActivity extends AppCompatActivity implements View.OnTouchListener {
float dX;
float dY;
int lastAction;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final View dragView = findViewById(R.id.draggable_view);
dragView.setOnTouchListener(this);
}
@Override
public boolean onTouch(View view, MotionEvent event) {
switch (event.getActionMasked()) {
case MotionEvent.ACTION_DOWN:
dX = view.getX() - event.getRawX();
dY = view.getY() - event.getRawY();
lastAction = MotionEvent.ACTION_DOWN;
break;
case MotionEvent.ACTION_MOVE:
view.setY(event.getRawY() + dY);
view.setX(event.getRawX() + dX);
lastAction = MotionEvent.ACTION_MOVE;
break;
case MotionEvent.ACTION_UP:
if (lastAction == MotionEvent.ACTION_DOWN)
Toast.makeText(DraggableView.this, "Clicked!", Toast.LENGTH_SHORT).show();
break;
default:
return false;
}
return true;
}
}
和XML：
<ImageButton
android:id="@+id/draggable_view"
android:background="@mipmap/ic_launcher"
android:layout_gravity="bottom|right"
android:layout_marginBottom="20dp"
android:layout_marginEnd="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
你可以做任何视图可拖动和点击。
尝试这个：
public class MainActivity extends AppCompatActivity implements View.OnTouchListener, View.OnDragListener , View.OnClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final View dragView = findViewById(R.id.draggable_view);
dragView.setOnTouchListener(this);
dragView.setOnclickListener(this);
}
@Override
public boolean onTouch(View v, MotionEvent event) {
//if move detected it start Drag event and it's handler or click wil be handled by click listener
if(event.getAction() == MotionEvent.ACTION_MOVE){
View.DragShadowBuilder mShadow = new View.DragShadowBuilder(v);
dragView = v;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
v.startDragAndDrop(null, mShadow, null, 0);
} else {
v.startDrag(null, mShadow, null, 0);
}
}
return false;
}
@Override
public void onClick(View view) {
switch (view.getId()){
case R.id.draggable_view:{
showToast("click detected");
}
break;
}
}
}
