Android 模拟按键，模拟触摸点击，模拟滑动

 （1）模拟按键发送事件

1.1 在dispatchKeyvent中直接替换按键Code

@Override
    public boolean dispatchKeyEvent(KeyEvent event) {
        //有些定制机没有左右键,用上下键和音量加减键模拟左右键，控制音量大小。
        if (event.getKeyCode() == KeyEvent.KEYCODE_DPAD_UP) {
            event.setKeyCode(KeyEvent.KEYCODE_DPAD_RIGHT);
        } else if (event.getKeyCode() == KeyEvent.KEYCODE_DPAD_DOWN) {
            event.setKeyCode(KeyEvent.KEYCODE_DPAD_LEFT);
        }else if(event.getKeyCode() == KeyEvent.KEYCODE_VOLUME_UP){//音量上键
            event.setKeyCode(KeyEvent.KEYCODE_DPAD_RIGHT);//右键
        }else if(event.getKeyCode() == KeyEvent.KEYCODE_VOLUME_DOWN){
            event.setKeyCode(KeyEvent.KEYCODE_DPAD_LEFT);
        }
        return super.dispatchKeyEvent(event);
    }

1.2 监听某个按键，替换按键code

mTitle.setOnKeyListener(new View.OnKeyListener() {
            @Override
            public boolean onKey(View view, int i, KeyEvent keyEvent) {
                //返回键专门用来返回,删除功能由A3完成.
                if(KeyEvent.KEYCODE_BACK == keyEvent.getKeyCode()){
                    onBackPressed();
                    return true;
                }

                //A3专门作为删除字符串作用.
                if(KeyEvent.KEYCODE_A3 == keyEvent.getKeyCode() && KeyEvent.ACTION_DOWN == keyEvent.getAction()){
                    keyEvent.setKeyCode(KeyEvent.KEYCODE_DEL);//删除字符串
                    mTitle.dispatchKeyEvent(keyEvent);
                    return true;
                }
                return false;
            }
        });

简单的代码，记录一下。

（2）模拟触摸点击，和模拟滑动，有些场景可能会用到。
   @Override
    public boolean onKeyUp(int keyCode, KeyEvent event) {
        WindowManager win=getWindowManager();
        Display display=win.getDefaultDisplay();
        int width=display.getWidth();
        int height=display.getHeight();

        if(keyCode==KeyEvent.KEYCODE_DPAD_CENTER){
            //点击屏幕中点
            setMouseClick(width/2,height/2);
        }else if(keyCode==KeyEvent.KEYCODE_DPAD_RIGHT){
            //向右滑动屏幕
            onFling(width/2,height/2,"right");
        }else if(keyCode==KeyEvent.KEYCODE_DPAD_LEFT){
            //向左滑动屏幕
            onFling(width/2,height/2,"left");
        }
        return super.onKeyUp(keyCode, event);
    }

   //模拟触摸点击
    public void setMouseClick(int x, int y){
        MotionEvent evenDownt = MotionEvent.obtain(System.currentTimeMillis(),
                System.currentTimeMillis() + 100, MotionEvent.ACTION_DOWN, x, y, 0);
        dispatchTouchEvent(evenDownt);
        MotionEvent eventUp = MotionEvent.obtain(System.currentTimeMillis(),
                System.currentTimeMillis() + 100, MotionEvent.ACTION_UP, x, y, 0);
        dispatchTouchEvent(eventUp);
        evenDownt.recycle();
        eventUp.recycle();
    }

    //模拟滑动
    public void onFling(final int x, final int y,final String leftRight){
        new Thread(new Runnable() {
            @Override
            public void run() {
                Instrumentation inst = new Instrumentation();
                long dowTime = SystemClock.uptimeMillis();
                int distance=0;
                if(leftRight.equals("right")){//right,next
                    distance=x-20;
                }else{//left,previous
                    distance=x+20;
                }
                inst.sendPointerSync(MotionEvent.obtain(dowTime,dowTime,
                        MotionEvent.ACTION_DOWN, x, y,0));
                inst.sendPointerSync(MotionEvent.obtain(dowTime,dowTime,
                        MotionEvent.ACTION_MOVE, x, y,0));
                inst.sendPointerSync(MotionEvent.obtain(dowTime,dowTime+20,
                        MotionEvent.ACTION_MOVE, distance, y,0));
                inst.sendPointerSync(MotionEvent.obtain(dowTime,dowTime+20,
                        MotionEvent.ACTION_UP, distance, y,0));
                inst.setInTouchMode(false);//如果是键盘机，不能是触摸模式，否则无焦点
            }
        }).start();
    }
