android - TextView - setCustomSelectionActionModeCallback 如何为多个 TextView 选择文本时创建 ActionMode.Callback

Question

我的系统中有几个 TextView，其中大部分我必须调用我的自定义 ActionMode.Callback。

问题是如何创建带有自定义 ActionMode.Callback 的 TextView？

今天我的代码就是这样

mTxOne.setCustomSelectionActionModeCallback(new MarkTextSelectionActionModeCallback());
 mTxTwo.setCustomSelectionActionModeCallback(new MarkTextSelectionActionModeCallback());
...

Answer 1

public class TextViewA extends TextView {

    @Override
    protected void onCreateContextMenu(ContextMenu menu) {
        super.onCreateContextMenu(menu);
        setCustomSelectionActionModeCallback(new MarkTextSelectionActionModeCallback());
    }



public TextViewA(Context context) {
    super(context);
}
public TextViewA(Context context,AttributeSet attrs) {
    super(context,attrs);
}
public TextViewA(Context context, AttributeSet attrs, int defStyle){
    super(context, attrs, defStyle);
}

这里是xml

 <RelativeLayout      xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

  <br.com.vrbsm.textviewexample.TextViewA
      android:id="@+id/textView2" 
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textIsSelectable="true"
      android:textSize="12dp"
      />
</RelativeLayout>

这里主要

public class MainActivity extends Activity{
//  
    private TextViewA textview;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);

        textview = (TextViewA)findViewById(R.id.textView2);
        textview.setText("Android is crazy");

    }


public class MarkTextSelectionActionModeCallback implements Callback {
