启动然后退出 onCreate onStart onResume onWindowFocusChanged: hasFocus: true onWindowFocusChanged: hasFocus...: true // 按home键 Act1: onWindowFocusChanged: hasFocus: false Act1: onPause Act1: onStop // 再回来 Act1...: onRestart Act1: onStart Act1: onResume Act1: onWindowFocusChanged: hasFocus: true // 按返回键退出act Act1...: hasFocus: true Act1: onStop Act2: onWindowFocusChanged: hasFocus: false Act2: onPause Act1: onRestart...onWindowFocusChanged: hasFocus: false onWindowFocusChanged: hasFocus: true 这里也可以用DialogFragment来做测试。
setContentView(R.layout.activity_main); } @Override public void onWindowFocusChanged(boolean hasFocus...) { super.onWindowFocusChanged(hasFocus); if (hasFocus && Build.VERSION.SDK_INT >= 19) {...代码解释: 1、 onWindowFocusChanged(boolean hasFocus) 方法 Activity生命周期,可以理解为走到这个方法的时候,activity才是真正意义上的显示...当activity显示在栈顶,和用户交互的时候,是有焦点的,hasFocus 为 true 当activity退出栈顶,不和用户交互的时候,是没有焦点的,hasFocus 为 false
在onWindowFocusChanged(boolean hasFocus)中获取为好 即覆写Activity的onWindowFocusChanged(boolean hasFocus)方法 XXX_Activity...: @Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged...(hasFocus); int[] location1 = new int[2] ; view.getLocationInWindow(location1); //获取在当前窗口内的绝对坐标
代码实现 在加载布局成功初始化无网络页面 @Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged...(hasFocus); if (hasFocus) { initNoNetView(R.id.id_xrv,R.id.rv); } } 需要一个工具类用来获取网络状态...整体代码 private boolean haveShowNetView = false; @Override public void onWindowFocusChanged(boolean hasFocus...) { super.onWindowFocusChanged(hasFocus); if (hasFocus) { initNoNetView(R.id.id_xrv,R.id.rv
方法1 - 在Activity的onWindowFocusChanged获取宽高 @Override public void onWindowFocusChanged(boolean hasFocus)...{ super.onWindowFocusChanged(hasFocus); // 在这里我们可以获取到View的真实宽高 Log.d(TAG, "onWindowFocusChanged...@Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus
super.onTouchEvent(event); } /** * activity显示到屏幕则开启动画 */ @Override public void onWindowFocusChanged(boolean hasFocus...) { // TODO Auto-generated method stub super.onWindowFocusChanged(hasFocus); if (hasFocus) loadingAnimation.start...所以,如果想启动界面就自动运行动画,可以在OnWindowFocusChanged(boolean hasFocus)中启动动画。
启动然后退出 onCreate onStart onResume onWindowFocusChanged: hasFocus: true onWindowFocusChanged: hasFocus...: true // 按home键 Act1: onWindowFocusChanged: hasFocus: false Act1: onPause Act1: onStop // 再回来 Act1...[Life]: onCreate [Life]: onStart [Life]: onResume [Life]: onWindowFocusChanged: hasFocus: true // 横屏...: hasFocus: true Act1: onStop Act2: onWindowFocusChanged: hasFocus: false Act2: onPause Act1: onRestart...onWindowFocusChanged: hasFocus: false onWindowFocusChanged: hasFocus: true 这里也可以用 DialogFragment 来做测试
所以重写onWidowFocusChanged方法: @Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged...(hasFocus); if(hasFocus){ vStepsHorizonListview.setSelection(position); } } 这样问题就完美解决了,,希望能帮助到各位!
方式二: activity属性不用设置,直接在activity中加入如下方法: @Override public void onWindowFocusChanged(boolean hasFocus)...{ super.onWindowFocusChanged(hasFocus); if( hasFocus ) { hideNavigationBar(); } } private
item.imgDescribe = value } } etContent.setOnFocusChangeListener{_,hasFocus...-> if (hasFocus){ etContent.addTextChangedListener(contentWatcher)...etContent.removeTextChangedListener(contentWatcher) } } imgDescribe.setOnFocusChangeListener{_,hasFocus...-> if (hasFocus){ imgDescribe.addTextChangedListener(describeWatcher)
setContentView(R.layout.activity_test); } @Override public void onWindowFocusChanged(boolean hasFocus...) { super.onWindowFocusChanged(hasFocus); Loger.e("==onWindowFocusChanged==",TAG + hasFocus...); if(hasFocus) { if(isFirstInWindowFocusChanged){ isFirstInWindowFocusChanged
getDecorView().setSystemUiVisibility(uiFlags); } @Override public void onWindowFocusChanged(boolean hasFocus...) { super.onWindowFocusChanged(hasFocus); if( hasFocus ) { hideNavigationBar(); } } 另外,在切换到
@Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus)...; if (hasFocus) { int width = view.getMeasuredWidth(); int height = view.getMeasuredHeight(
的焦点变化改变图片的显示与否,输入框里的字符串长度如果大于0,显示,否则隐藏 * by Hankkin at:2015年8月11日 16:32:47 * @param v * @param hasFocus...*/ @Override public void onFocusChange(View v, boolean hasFocus) { if (hasFocus
Build.VERSION_CODES.KITKAT) @Override public void onFocusChange(View v, boolean hasFocus...) { // 当hasFocus = true 是获取焦点 if (hasFocus && !...Build.VERSION_CODES.KITKAT) @Override public void onFocusChange(View v, boolean hasFocus...) { // 当hasFocus = true 是获取焦点 if (hasFocus && !
目前经过测试可用的方法是: /* * 对于:Activity * 覆写 onWindowFocusChanged(boolean hasFocus)方法 */ @Override...public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus);
滑动实现了,但启停时机也很重要 所以这里选用onWindowFocusChanged因为它在窗体失去和获得焦点的时候会通知我们 override fun onWindowFocusChanged(hasFocus...: Boolean) { super.onWindowFocusChanged(hasFocus) if (hasFocus){ bannerVp.postDelayed
focusChanger = new OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus...hasFocus && myAddress.getStreet().length() > 0) { jiequText.setVisibility(View.GONE... jiequTextView.setText(myAddress.getStreet()); } if (hasFocus...hasFocus && myAddress.getName().length() > 0) { nameText.setVisibility(View.GONE...hasFocus && myAddress.getPhone().length() > 0) { phoneText.setVisibility(View.GONE
getDefaultDisplay().getMetrics(mDisplayMetrics); } @Override public void onWindowFocusChanged(boolean hasFocus...) { super.onWindowFocusChanged(hasFocus); if(hasFocus&&mPaintView==null){ int screenWidth
