代码实现 public class RocketService extends Service { private WindowManager mWM; private View view; private...); mWM = (WindowManager) getSystemService(WINDOW_SERVICE ); winWidth = mWM.getDefaultDisplay(). getWidth...(); winHeight = mWM .getDefaultDisplay().getHeight (); params = new WindowManager.LayoutParams(); params...); } @Override public void onDestroy() { // TODO Auto-generated method stub super .onDestroy(); if (mWM...= null) { mWM.removeView( view); view = null ; } } } 以上就是本文的全部内容，希望对大家的学习有所帮助。
View来加载一个布局，为了侧重悬浮窗界面，我直接使用TextView演示 private void initFloatWindow() { if (mShow == null) { mWm...(mShow, mParams); 2.4 悬浮窗隐藏 mWm.removeView(mShow); 2.5 完整示例代码 package com.wu.sufadi; import android.app.Activity...void handleMessage(Message msg) { super.handleMessage(msg); switch (msg.what) { case MSG_SHOW_WINDOW: mWm.addView...(mShow, mParams); break; case MSG_HIDE_WINDOW: mWm.removeView(mShow); break; default: break; } } }; private...handler.sendEmptyMessage(MSG_HIDE_WINDOW); } private void initFloatWindow() { if (mShow == null) { mWm
mHorizontalMargin; private float mVerticalMargin; private View mView; private View mNextView; private WindowManager mWM...android.R.style.Animation_Toast; params.type = WindowManager.LayoutParams.TYPE_TOAST; params.setTitle("Toast"); mWM...= mNextView) { // remove the old view if necessary handleHide(); mView = mNextView; // mWM = WindowManagerImpl.getDefault...= null) { mWM.removeView(mView); } mWM.addView(mView, mParams); } } private void handleHide() { if...= null) { mWM.removeView(mView); } mView = null; } } } 测试类的代码如下： package com.open.toast; import android.app.Activity
="5dp" android:padding="10dp" / 封装的工具类 public class AddressToast { private WindowManager mWm...public AddressToast(Context context){ this.mContext = context; // 1 获取WindowManger 对象 mWm...View.inflate(mContext, R.layout.view_toast, null); // 5 WindowManager:addView(view,params); mWm.addView...= null) { mWm.removeView(mV); } mV = null; } } } 调用工具类的逻辑: public void clickMe2...=null){ mWm.removeView(mV); } mV=null; } } 对产生的view设置接触监听事件 刚刚的弹出的window还不能移动
查看Toast的handleShow方法(api27和api25)，发现是因为 mWM.addView(mView, mParams); 这一段代码在 25 没有 try catch，而 27 是加了...* * @param toast 发生异常的Toast实例 */ void onBadTokenCaught(@NonNull Toast toast); } 2.mWM.addView...添加try-catch 注意这三句代码 Context context = mView.getContext().getApplicationContext(); mWM = (WindowManager...)context.getSystemService(Context.WINDOW_SERVICE); mWM.addView(mView, mParams); 从下往上，我们需要 (1)WindowManager...WindowManagerWrapper(WindowManager readImpl) { mImpl = readImpl; } /** * mWM.addView
context == null) { context = mView.getContext(); } mWM...--关键点1--> mWM.removeView(mView); } if (localLOGV)...= null) { mWM.removeView(mView); } mView = null;...} } } 其show函数，归根到底就是通过WindowManagerService，将View添加到Window， mWM.addView(mView..." + mView + " in " + this); mWM.removeView(mView); } mView =
