Android中的onTouch（）事件如何区分单击事件和滑动事件


private boolean isDown = false;

private float x1 = 0;

private float x2 = 0;

private float y1 = 0;

private float y2 = 0;

@Override

public boolean onTouch(View v, MotionEvent event) {

break;

case MotionEvent.ACTION_UP:

isDown = false;

break;

case MotionEvent.ACTION_MOVE:

x2 = event.getX();

y2 = event.getY();

break;

default:

break;

}

switch (v.getId()) {

case R.id.button_say:

if (event.getAction() == MotionEvent.ACTION_DOWN) {

StartTalk();

StopAudio();

// voiceChangeBtn.setImageResource(R.drawable.ptz_microphone_on1);

} else if (event.getAction() == MotionEvent.ACTION_UP) {

StopTalk();

StartAudio();

// voiceChangeBtn.setImageResource(R.drawable.ptz_microphone_on);

}

break;
