Android simulated clicks

Android simulated clicks
Introduction

One click event can be simulated in Android by simulating MotionEvent. The other is implemented by ADB.

First, the general method for simulating MotionEvent is as follows:

private void setSimulateClick(View view, float x, float y) {long downTime = SystemClock.uptimeMillis();final MotionEvent downEvent = MotionEvent.obtain(downTime, downTime,MotionEvent.ACTION_DOWN, x, y, 0);downTime += 1000;final MotionEvent upEvent = MotionEvent.obtain(downTime, downTime,MotionEvent.ACTION_UP, x, y, 0);view.onTouchEvent(downEvent);view.onTouchEvent(upEvent);downEvent.recycle();upEvent.recycle();}

Demo:

package com.xys.simulateevent;import android.app.Activity;import android.os.Bundle;import android.os.SystemClock;import android.view.MotionEvent;import android.view.View;import android.widget.Button;import android.widget.Toast;public class MainActivity extends Activity {Button button;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);button = (Button) findViewById(R.id.button1);}public void clickeMe(View view) {Toast.makeText(this, "clicked", Toast.LENGTH_LONG).show();}public void simulate(View view) {setSimulateClick(button, 160, 100);}private void setSimulateClick(View view, float x, float y) {long downTime = SystemClock.uptimeMillis();final MotionEvent downEvent = MotionEvent.obtain(downTime, downTime,MotionEvent.ACTION_DOWN, x, y, 0);downTime += 1000;final MotionEvent upEvent = MotionEvent.obtain(downTime, downTime,MotionEvent.ACTION_UP, x, y, 0);view.onTouchEvent(downEvent);view.onTouchEvent(upEvent);downEvent.recycle();upEvent.recycle();}}

Second, ADB controls ADB through input to input events such as touch and key:

The sources are:       trackball      joystick      touchnavigation      mouse      keyboard      gamepad      touchpad      dpad      stylus      touchscreenThe commands and default sources are:      text 
 
   (Default: touchscreen)      keyevent [--longpress] 
  
    ... (Default: keyboard)      tap 
    
    
      (Default: touchscreen)      swipe 
      
       
        
        
          [duration(ms)] (Default: touchscreen) press (Default: trackball) roll 
          
          
            (Default: trackball)
