单击Button时未调用Activity的onTouchEvent()

Question

我想在Activity.onTouchEvent()方法中做一些B.logic .它适用于TextView其他不可点击的视图.然而,它并没有被称为点击Button.但我也需要这个.

这是代码.

public class MainActivity extends Activity {
    private static final String TAG = MainActivity.class.getSimpleName();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        findViewById(R.id.button1).setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "Oh shit!! click performed... :(", Toast.LENGTH_LONG).show();

            }
        });



    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        Log.d(TAG, "ssssssssssssssssssssssss:touch");
        return super.onTouchEvent(event);
    }

    public boolean dispatchTouchEvent(MotionEvent event) {
        int eventaction=event.getAction();

        switch(eventaction) {
        case MotionEvent.ACTION_MOVE:
            break;
        default:
            break;
        }

        return super.dispatchTouchEvent(event);
    }

}

请帮我解决这个问题.

我根据需要使用了dispatchTouchEvent(MotionEvent ev).这是解决方案.

private boolean isInSideClicked = false;
    public boolean dispatchTouchEvent(MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_DOWN) {
            View content = findViewById(R.id.textView1);
            int[] contentLocation = new int[2];
            content.getLocationOnScreen(contentLocation);
            Rect rect = new Rect(contentLocation[0], 
                                 contentLocation[1], 
                                 contentLocation[0] + content.getWidth(), 
                                 contentLocation[1] + content.getHeight());

            View frame = findViewById(R.id.editText1);
            int[] frameLocation = new int[2];
            frame.getLocationOnScreen(frameLocation);
            Rect framerect = new Rect(frameLocation[0], 
                    frameLocation[1], 
                    frameLocation[0] + frame.getWidth(), 
                    frameLocation[1] + frame.getHeight());
            Log.d(TAG, "rect:  "+rect.bottom+" , "+rect.top+" , "+rect.left+" , "+rect.right);
            Log.d(TAG, "FrameRect:  "+framerect.bottom+" , "+framerect.top+" , "+framerect.left+" , "+framerect.right);
            Log.d(TAG, "x: "+event.getX()+"  y: "+event.getY());

            if((rect.contains((int)event.getX(), (int)event.getY()) || framerect.contains((int)event.getX(), (int)event.getY()) ) ) {
                isInSideClicked = true;
            }
            if(isInSideClicked){
                return super.dispatchTouchEvent(event); 
            }else{
                return true;
            }
        }else if(event.getAction() == MotionEvent.ACTION_UP && isInSideClicked) {
            isInSideClicked = false;
            return super.dispatchTouchEvent(event);
        }else if(event.getAction() == MotionEvent.ACTION_MOVE && isInSideClicked) {
            return super.dispatchTouchEvent(event);
        }else{
            isInSideClicked = false;
            return true;    
        }
    }

下面是OS级别如何处理触摸事件的层次结构.

Activity.dispatchTouchEvent()
ViewGroup.dispatchTouchEvent()
View.dispatchTouchEvent()
View.onTouchEvent()
ViewGroup.onTouchEvent()
Activity.onTouchEvent()

有了这个,我限制了不在必需的布局/视图中的视图的触摸事件.
