     阅读此文建议先阅读 安卓Tv开发(二)移动智能电视之焦点控制(按键事件)     接触TV的的开发,操作体验是我们开发者必须要关注的,因此,遥控器做鼠标成了智能设备的开发主流不可缺少的一部分,今天给大家带来怎样实现遥控操作模拟鼠标的功能,觉得ok的请到下方自觉的点个赞。有自动化测试框架也有用此方式实现的。   实现功能: 遥控器方向键控制鼠标箭头移动                       遥控器可以操作模拟鼠标进行点击操作。  效果图:
    实现之前先做个大致分析,记得之前我在一篇安卓实现高仿Ios桌面的博客中就接触过类似此需求的功能,第一眼大家觉得可拖动gridview和实现遥控器拖动鼠标有啥关系,仔细一分析,其实异曲同工,可拖动的gridView我们是用手指进行item移动的,而这次的模拟鼠标我们可以把它想成一个item(只不过展现的UI为一个鼠标箭头的图片),用遥控器进行控制的,当然我们无需拖动,用遥控方向键来控制item的位移即可。至于遥控器点击OK键进行点击执行点击操作的事件,我们可以获取模拟鼠标在屏幕中的绝对坐标,然后模拟一个此处的点击事件即可。

      一 自定义鼠标视图

        用于展现鼠标的具体视图,MouseView 继承 FrameLayout ,之后漂浮在控制的activity上,只要由WindowManage控制此视图的展现和移动。public MouseView(Context context) { super(context); } public MouseView(Context context, MouseManager mMouseMrg) { super(context); init( mMouseMrg); } public OnMouseListener getOnMouseListener() { return mOnMouseListener; } public void setOnMouseListener(OnMouseListener mOnMouseListener) { this.mOnMouseListener = mOnMouseListener; } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); if (mMouseView != null && mMouseBitmap != null) { mMouseView.measure(MeasureSpec.makeMeasureSpec(mMouseBitmap.getWidth(), MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(mMouseBitmap.getHeight(), MeasureSpec.EXACTLY)); } } private void init(MouseManager manager) { mMouseManager = manager; Drawable drawable = getResources().getDrawable( R.drawable.shubiao); mMouseBitmap = drawableToBitamp(drawable); mMouseView = new ImageView(getContext()); mMouseView.setImageBitmap(mMouseBitmap); addView(mMouseView, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); mOffsetX = (int)((mMouseBitmap.getWidth())); mOffsetY = (int)((mMouseBitmap.getHeight())); } @Override protected void onLayout(boolean changed, int left, int top, int right, int bottom) { if(mMouseView != null) { mMouseView.layout(mMouseX, mMouseY, mMouseX + mMouseView.getMeasuredWidth(), mMouseY + mMouseView.getMeasuredHeight()); } }

     二 鼠标控制器

      用来处理点击事件,和鼠标移动事件。主要是重写事件分发方法 dispatchKeyEvent(KeyEvent event),用于控制鼠标移动和点击。   /** * @param parent * @param type */ public void init(ViewGroup parentView, int type) { mParentView = parentView; mContext = parentView.getContext(); mMouseView = new MouseView(mContext, this); mMouseView.setOnMouseListener(this); mCurrentType = type; } /** * @return */ public boolean getMouseType() { return isMouseType; } /** * @return */ public int getCurrentActivityType() { return mCurrentType; } /** * showmouse */ public void showMouseView() { ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT); if(mMouseView != null) { mParentView.addView(mMouseView, lp); } } public boolean onDpadClicked(KeyEvent event) { if(!isMouseType) { return false; } if(event.getKeyCode() == KEYCODE_CENTER) { dispatchKeyEventToMouse(event); } else { if(event.getAction() == KeyEvent.ACTION_DOWN) { if(!isKeyEventCousumed) { if(event.getDownTime() - mLastEventTime < defTimes) { if(mSpeed < defMaxSpeed) { mSpeed ++; } } else { mSpeed = 1; } } mLastEventTime = event.getDownTime(); dispatchKeyEventToMouse(event); isKeyEventCousumed = true; } else if(event.getAction() == KeyEvent.ACTION_UP) { if(!isKeyEventCousumed){ dispatchKeyEventToMouse(event); } isKeyEventCousumed = false; } } return true; } public void sendCenterClickEvent(int x, int y, int action) { sendMotionEvent(x, y, action); } @SuppressLint("InlinedApi") public void sendMouseHoverEvent(int downx, int downy) { sendMotionEvent(downx, downy, MotionEvent.ACTION_HOVER_MOVE); } @TargetApi(Build.VERSION_CODES.HONEYCOMB_MR1) @SuppressLint("NewApi") private void sendMotionEvent(int x, int y, int action) { MotionEvent motionEvent = getMotionEvent( x, y ,action) ; if(action == MotionEvent.ACTION_HOVER_MOVE) { motionEvent.setSource(InputDevice.SOURCE_CLASS_POINTER); mMouseView.dispatchGenericMotionEvent(motionEvent); //mParentView.dispatchGenericMotionEvent(motionEvent); } else { //mParentView.dispatchTouchEvent(motionEvent); mMouseView.dispatchTouchEvent(motionEvent); } } private MotionEvent getMotionEvent(int downx, int downy, int action) { // TODO Auto-generated method stub long downTime = SystemClock.uptimeMillis(); long eventTime = SystemClock.uptimeMillis(); int metaState = 0; return MotionEvent.obtain( downTime, eventTime, action, downx, downy, metaState ); } @Override public boolean onclick(View v, KeyEvent et) { if (getMouseType()) { return onDpadClicked(et); } return mParentView.dispatchKeyEvent(et); }          

     三 当前页面加入鼠标

         如果某个activity需要加入鼠标,只要初始化 MouseManager,然后设置当先鼠标显示即可,本次为了方便操作和直观的显示,加入一个webView加载网页,用于鼠标控制操作。public class MainActivity extends Activity { WindowManager wm; WindowManager.LayoutParams params; private MouseManager mMouseManager; public static ViewGroup contentView; private WebView webView; private View mLoginStatusView; private TextView mLoaddingMessageView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LayoutInflater inflater = getLayoutInflater(); contentView = (ViewGroup) inflater.inflate(R.layout.test, null); setContentView(contentView); init(); initMouse(); showMouse(); } private void init() { webView = (WebView) contentView.findViewById(R.id.web); mLoginStatusView = this.findViewById(R.id.login_status); mLoaddingMessageView = (TextView) this .findViewById(R.id.login_status_message); Button button = (Button) contentView.findViewById(R.id.btn_onclick); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(MainActivity.this, "onclicked ", 1).show(); showProgress(true); webView.setVisibility(View.VISIBLE); webView.loadUrl("https://www.baidu.com/"); WebSettings settings = webView.getSettings(); settings.setJavaScriptEnabled(true); webView.setWebViewClient(new WebViewClient() { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } @Override public void onPageFinished(WebView view, String url) { super.onPageFinished(view, url); } @Override public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { Toast.makeText(MainActivity.this, "加载失败 ", Toast.LENGTH_LONG).show(); super.onReceivedError(view, errorCode, description, failingUrl); } }); webView.setWebChromeClient(new WebChromeClient() { @Override public void onProgressChanged(WebView view, int newProgress) { // TODO Auto-generated method stub if (newProgress == 100) { showProgress(false); } else { } } }); } }); } @SuppressLint("NewApi") private void showProgress(final boolean show) { // On Honeycomb MR2 we have the ViewPropertyAnimator APIs, which allow // for very easy animations. If available, use these APIs to fade-in // the progress spinner. if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) { int shortAnimTime = getResources().getInteger( android.R.integer.config_shortAnimTime); mLoginStatusView.setVisibility(View.VISIBLE); mLoginStatusView.animate().setDuration(shortAnimTime) .alpha(show ? 1 : 0) .setListener(new AnimatorListenerAdapter() { @Override public void onAnimationEnd(Animator animation) { webView.setVisibility(show ? View.VISIBLE : View.GONE); } }); webView.setVisibility(View.VISIBLE); webView.animate().setDuration(shortAnimTime).alpha(show ? 0 : 1) .setListener(new AnimatorListenerAdapter() { @Override public void onAnimationEnd(Animator animation) { webView.setVisibility(show ? View.GONE : View.VISIBLE); } }); } else { // The ViewPropertyAnimator APIs are not available, so simply show // and hide the relevant UI components. mLoginStatusView.setVisibility(show ? View.VISIBLE : View.GONE); webView.setVisibility(show ? View.GONE : View.VISIBLE); } } private void showMouse() { mMouseManager.showMouseView(); } public void initMouse() { initMouseMrg(); } public void initMouseMrg() { mMouseManager = new MouseManager(); mMouseManager.init(contentView, MouseManager.MOUSE_TYPE); mMouseManager.setshowMouse(true); } }
     简单三步,代码就可以实现简单的用于遥控器操作的TV的浏览器,本次demo只是用户手动模拟点击,至于实现自动化模拟点击,以上方式显得极为笨拙,  如果实现自动化测试或者模拟点击事件 ,采用Instrumentation代理,而Instrumentation不需要一定的activity展现,我们可以将它理解为一种没有图形界面的,具有启动能力的,用于监控其他类(用Target Package声明)的工具类。Instrumentation开发者可以构建一个独立于应用程序的代理程序(Agent),用来监测和协助运行在 JVM 上的程序,甚至能够替换和修改某些类的定义。有了这样的功能,我们就可以实现更为灵活的运行时虚拟机监控和 Java 类操作,代替人为操作,主要用于自动测试框架。
    instrumentation发送键盘鼠标事件:Instrumentation提供了丰富的以send开头的函数接口来实现模拟键盘和鼠标,如下所述:      sendCharacterSync(int keyCode)            //用于发送指定KeyCode的按键     sendKeyDownUpSync(int key)                //用于发送指定KeyCode的按键    sendPointerSync(MotionEvent event)     //用于模拟Touch     sendStringSync(String text)                   //用于发送字符串    发发送一条模拟点击事件
  1. Instrumentation inst=new Instrumentation();  
  2. inst.sendPointerSync(MotionEvent.obtain(SystemClock.uptimeMillis(),SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, 10100));  
  3. inst.sendPointerSync(MotionEvent.obtain(SystemClock.uptimeMillis(),SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, 10100));  
    具体逻辑是当我的app启动时 。就可以用全局的Instrumentation来监控到底当前在哪个界面,提前将点击的入口定义OK后,接下来的点击事件就如同用户主动点击一样,包括跳转逻辑不再需要考虑。     当然现在安卓也可以采用辅助功能实现监控某个界面 遍历界面的view元素实现模拟点击操作,有兴趣的朋友可以去看下辅助自动装(http://blog.csdn.net/sk719887916/article/details/46746991)和微信自动枪红包的demo,实现方式比简单,这里就不再分享了。   尊重原创:本文出处     本文出处:http://blog.csdn.net/sk719887916/article/details/40348853,作者:skay ,欢迎阅读。
