我正在尝试创建一些组件的自定义视图,因为我在我的应用程序中需要这么多组合。除了我的progressBar
的进展外,代码中的所有内容都有效。我认为它没有正确获得XML
文件的值。
在我的init void中,我调用setProgressBar(progress)
为我的xml文件提供当前值。当我输入例如'setProgressBar(88)
'时,它可以很好地工作,但不能使用必须在xml文件中找到的值。
custom progress bar.Java
public class CustomProgressbar extends RelativeLayout {
@StyleableRes
int index0 = 0;
@StyleableRes
int index1 = 1;
@StyleableRes
int index2 = 2;
TextView titleText;
TextView valueText;
ProgressBar progressBar;
public CustomProgressbar(Context context, AttributeSet attrs) {
super(context, attrs);
init(context, attrs);
}
private void init(Context context, AttributeSet attrs) {
inflate(context, R.layout.custom_progressbar_layout, this);
int[] sets = {R.attr.title, R.attr.value, R.attr.progress};
TypedArray typedArray = context.obtainStyledAttributes(attrs, sets);
CharSequence title = typedArray.getText(index0);
CharSequence value = typedArray.getText(index1);
int progress = typedArray.getInteger(index2,0);
typedArray.recycle();
titleText = findViewById(R.id.title_text);
valueText = findViewById(R.id.value_text);
progressBar = findViewById(R.id.progressbar_attr);
setTitleText(title);
setValueText(value);
setProgressBar(progress);
}
public CharSequence getTitleText() {
return titleText.getText();
}
public CharSequence getValueText() {
return valueText.getText();
}
public int getProgressBar() {
return progressBar.getProgress();
}
public void setTitleText(CharSequence value) {
titleText.setText(value);
}
public void setValueText(CharSequence value) {
valueText.setText(value);
}
public void setProgressBar(int value) {
progressBar.setProgress(value);
}
}

app:title="ThisIsTheTitle"
app:value="€ 28,30"
app:progress="77" />
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
而我的属性
<resources>
<declare-styleable name="CustomProgressbar">
<attr name="title" format="string"/>
<attr name="value" format="string"/>
<attr name="progress" format="integer"/>
</declare-styleable>
</resources>
目前的结果:
(我还不允许添加图片,所以我有链接。)
试试这个,样式属性正在以另一种方式进行
public class CustomProgressbar extends RelativeLayout {
private TextView titleText;
private TextView valueText;
private ProgressBar progressBar;
public CustomProgressbar(Context context, AttributeSet attrs) {
super(context, attrs);
init(context, attrs);
}
private void init(Context context, AttributeSet attrs) {
inflate(context, R.layout.custom_progressbar_layout, this);
TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.CustomProgressbar);
CharSequence title = typedArray.getText(R.styleable.CustomProgressbar_title);
CharSequence value = typedArray.getText(R.styleable.CustomProgressbar_value);
int progress = typedArray.getInteger(R.styleable.CustomProgressbar_progress, 0);
typedArray.recycle();
titleText = findViewById(R.id.title_text);
valueText = findViewById(R.id.value_text);
progressBar = findViewById(R.id.progressbar_attr);
setTitleText(title);
setValueText(value);
setProgressBar(progress);
}
public CharSequence getTitleText() {
return titleText.getText();
}
public CharSequence getValueText() {
return valueText.getText();
}
public int getProgressBar() {
return progressBar.getProgress();
}
public void setTitleText(CharSequence value) {
titleText.setText(value);
}
public void setValueText(CharSequence value) {
valueText.setText(value);
}
public void setProgressBar(int value) {
progressBar.setProgress(value);
}
}
