[Android Note] on the dial-up interface, you can call a specified number to start a secret interface.Solution Description: 1. listen to the user's call operations by registering a broadcast receiver; 2. when a user makes a call, the broadcast receiver receives the number and compares it with the specified "dark". If the number matches, an interface is started and

, when the interface jumps, remember to take this runnable to remove from the handler, otherwise it will bring unexpected results, and find a bug is not easy.There is another way to design the activity of the start mode, we are to start 2 of the same activity, and the activity has a boot mode is singletop, when the activated activity at the top of the stack will not start the activity, Let's set it down and try it,OK, design this android:launchmode =

Now assume that there are two classes Aclass.class and Bactivity.class, passing the value in a to the B call1, the code in Aclass.class is as followspublic class AClass implements { //Get interface Object private Onaclasslistener Aclasslistener; //Construction Method Private AClass () { } //Send data public void sends () {if (aclasslistener!= null) { aclasslistener.onaclass ("Pass the value Here"); } } For B-bound

structure in C (structures). However, the JVM specification does not define how objects are implemented in memory. If a given JVM is implemented in a layout object, and the local method assumes something different, then you have to rewrite the local method library.2. Because local methods can maintain a direct pointer to objects in the JVM, local methods in JDK1.0 adopt a conservative GC policy.The birth of JNI is to solve these two problems, it can be supported by the JVM under all platforms:1

I am doing web development, recently in learning Android. During the weekend, I want to write a delay into the main interface of the function, mainly used in handler and runnable, the code is as follows: packagecom.zx.app;importandroid.app.Activity;importandroid.content.Intent;import android.os.bundle;importandroid.os.handler;importandroid.view.view;import android.widget.button;publicclassstartscreenactivit

Android uses ViewPager to simulate the main interface-android learning Tour (78), viewpager-androidThe first step is to introduce the ViewPager control, which requires pagerAdapter to provide data as a container. The data source of pagerAdapter is the View array as follows: Some code is as follows: mPagerAdapter = new PagerAdapter(){ @Override

occupies 1/3 of the space. If you add a third view and the weight is set to 1, then the first view (with a weight of 2) occupies 1/2 of the space, and the remaining two view accounts for 1/4. (Note that the premise of the use of weights is generally set to 0DP for the width or height of the view, then the system calculates the space that the view should occupy according to the weight rules above.) However, in many cases, if the view is set to the Match_parent attribute, then the above calculati
