我正在尝试制作拖放按钮，它们位于同一个 xml 中，我为它们创建了两个 onTouchListener，它们可以拖放，但是如果我移动其中一个，另一个也会移动，有人可以告诉我如何解决这个问题？这是我的代码：
btn = (Button) findViewById(R.id.btn);
btn.setDrawingCacheEnabled(true);
btn.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View view, MotionEvent me) {
if (me.getAction() == MotionEvent.ACTION_DOWN) {
status = START_DRAGGING;
}
if (me.getAction() == MotionEvent.ACTION_UP) {
status = STOP_DRAGGING;
Log.i("Drag", "Stopped Dragging");
}
else if (me.getAction() == MotionEvent.ACTION_MOVE) {
if (status == START_DRAGGING) {
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
layoutParams.setMargins((int) me.getRawX() - 50,(int) me.getRawY() - 70, 0, 0);
layout.removeView(btn);
layout.addView(btn, layoutParams);
btn.invalidate();
}
}
return false;
}
});
btn1 = (Button) findViewById(R.id.btn1);
btn1.setDrawingCacheEnabled(true);
btn1.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View view1, MotionEvent me1) {
if (me1.getAction() == MotionEvent.ACTION_DOWN) {
status = START_DRAGGING;
}
if (me1.getAction() == MotionEvent.ACTION_UP) {
status = STOP_DRAGGING;
Log.i("Drag", "Stopped Dragging");
}
else if (me1.getAction() == MotionEvent.ACTION_MOVE) {
if (status == START_DRAGGING) {
LinearLayout.LayoutParams layoutParams1 = new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
layoutParams1.setMargins((int) me1.getRawX() - 50,(int) me1.getRawY() - 70, 0, 0);
layout.removeView(btn1);
layout.addView(btn1, layoutParams1);
btn1.invalidate();
}
}
return false;
}
}
);
