It's making a page 1-3 and calls them all together at the same time to activate. Can anybody tell me how I can call

I need to check a permission on a button press, and if it is successful, send a text message. When I grant permission to do it, the dialog closes, but it doesn't trigger the Send Text until I press the button again. I've debugged and set breakpoints in the onRequestPermissionsResult() method but it never goes into it. This method gets called first: private void askForPermission () { String [] permissions = new

When I run the "Allocations" instrument, it says I have about 2MB of "Live Bytes", and the figure stays roughly constant as I move through the app (spikes up to 3MB or so when the App is busy, but then drops back down to 2MB). But when I run the "Activity Monitory" instrument, my app's "Real Memory" is 25MB once it finishes launching, and grows rapidly whenever drawing occurs inside my CALayer. In

I'm using ConstraintLayout 1.1.3 and I'm setting the visibility of group in both XML layout and java code. But it does not change the visibility status. It is always visible. This is the layout file <?xml version="1.0" encoding="utf-8"?> <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"

What is the problem? Shouldn't importing the classes be enough? For eg, I import android.view.View for findViewById but it still makes no difference. Please advise. 回答1: you should pass the instance of your Activity to your Second Class on the constructor like this : In your Activity Instanciate your Class like this : MyClass instance =

Instead of: onAttach ( Activity activity ) It's now: onAttach ( Context context ) As my app uses the activity passed before deprecation, a possible solution i think is: @Override public void onAttach ( Context context ) { super . onAttach ( context ); activity = getActivity (); } Would that be the correct way to do it? UPDATE: If i run a device with API lower than 23, the new

Meaning I know I can do a lsactivity to list all elements in an activity with their respective versions and then in the easy world would be able to delete those versions. But the SCM policy does not permit us to delete/ rmver anything. So I am left with back merging 1 version back. Meaning let us say I have version 5 of a.java checked into an activity. One way I think to achieve this, is find

On some forums I've been suggested to set android:hardwareAccelerated="true" inside <application> and on other forums same attribute inside <activity> inside my AndroidManifest.xml . Below is the representation of what it looks like: <application ... android:hardwareAccelerated="true" ...> <activity ... android:hardwareAccelerated="true" ...> </activity> </application> I ended up setting in both, yet I wonder, which one is the right way, and what is the difference? 回答1

大家使用Android的原生UI都知道，Android的Activity跳转就是很生硬的切换界面。其实Android的Activity跳转可以设置各种动画。 通常，对Activity切换时加入过渡动画的方法是： 在 startActivity() 或 finish() ，加入以下这个方法 overridePendingTransition(enterAnim, exitAnim); 实现非常简单，用overridePendingtransition(int inId, int outId)即可实现。inId是下一界面进入效果的xml文件的id,outId是当前界面退出效果的xml文件id。 样例代码可从 http://iaiai.iteye.com/blog/1078318 下载 来源： oschina 链接： https://my.oschina.net/u/242041/blog/203661
