导论
在Android中模拟一个点击事件有三种方式是通过模拟MotionEvent来实现；一种是通过ADB来实现；一种是通过Instrumentation测试框架来实现
第一种：模拟MotionEvent
通用方法如下：
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;
@Override
protected 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();
}
}
第二种：ADB控制
ADB中通过input来实现，用于输入
touch，key等事件：
The sources are:
trackball
joystick
touchnavigation
mouse
keyboard
gamepad
touchpad
dpad
stylus
touchscreen
The commands and default sources are:
text <string> (Default: touchscreen)
keyevent [--longpress] <key code number or name> ... (Default: keyboard)
tap <x> <y> (Default: touchscreen)
swipe <x1> <y1> <x2> <y2> [duration(ms)] (Default: touchscreen)
press (Default: trackball)
roll <dx> <dy> (Default: trackball)
Demo 输入按键enter key：
adb shell input keyevent 66
Demo 输入输入滑动操作：
adb shell input touchscreen swipe 18 665 18 350
第三种：Instrumentation
Instrumentation是Android的测试框架，通过他，可以模拟很多Activity操作
//KeyEvent.KEYCODE_MENU
//KeyEvent.KEYCODE_BACK
public static void sendKeyEvent(final int KeyCode) {
new Thread() { //不可在主线程中调用
public void run() {
try {
Instrumentation inst = new Instrumentation();
inst.sendKeyDownUpSync(KeyCode);
} catch (Exception e) {
e.printStackTrace();
}
}
}.start();
}
第四种：通过使用sendevent
adb提供了控制手机的另一种实现：
sendevent [device] [type] [code] [value]
eg：229就是menu的type值
sendevent /dev/input/event0 1 229 1
sendevent /dev/input/event0 1 229 0
sendevent /dev/input/event0 1 229 0
这两句需要一起执行，因为一个点击事件包含down和up，不然不能执行操作
