Android 无法在listview项目中正确选择文本

我使用了这个方法android.text.Selection.setSelection（Spannable text，int index）来选择MyEditText中的一些文本，一个自定义类在移动手指的同时扩展了EditText。它在单个视图中工作得很好，但当我将它应用于ListView中的多个MyEditText项时，它无法正常工作

以下是我的代码，您也可以从github（）下载：

MyEditText.java

    public class MyEditText extends EditText {

    public MyEditText(Context context) {
        super(context);
        initialize();
    }

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

    public MyEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        initialize();
    }

    private void initialize() {
        setBackgroundColor(Color.WHITE);
    }

    @Override
    protected void onCreateContextMenu(ContextMenu menu) {
        // avoid to pop out the context menu
    }

    @Override
    public boolean getDefaultEditable() {
        return false;
    }

    private int offset;

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        int action = event.getAction();
        Layout layout = getLayout();
        int line = 0;
        switch (action) {
        case MotionEvent.ACTION_DOWN:
            line = layout.getLineForVertical(getScrollY() + (int) event.getY());
            offset = layout.getOffsetForHorizontal(line, (int) event.getX());
            Selection.setSelection(getEditableText(), offset);
            break;
        case MotionEvent.ACTION_MOVE:
        case MotionEvent.ACTION_UP:
            line = layout.getLineForVertical(getScrollY() + (int) event.getY());
            int curOff = layout
                    .getOffsetForHorizontal(line, (int) event.getX());
            Selection.setSelection(getEditableText(), offset, curOff);
            break;
        }
        return true;
    }

}

当你运行这个项目时，你会发现listview中只有第一个项目是可选择的，另一件奇怪的事情是你不能选择你所包围的所有文本

我的观点是onTouchEvent与listview的滚动运动不兼容，但对此我无能为力

真希望有人能帮我

我的意见是onTouchEvent与卷轴不兼容 listview的移动，但我对此无能为力

要解决此问题，请重写Activity.dispatchTouchEvent（）（），并将其传递给ListView，最终传递给视图。让它先做它的工作。然后让视图系统完成它的工作
