如何将默认图片放入android？ （启动画面）

Question

I'm developing an android application and I want to put a default picture. This is common in iPhone apps; when the app starts, it shows the name of the developer and the name of the application (for example) with an image.

I think that is possible because apps like Facebook have these default screens before the application starts. How can I implement these?

Answer 1

What you want is a splash screen:

Answer 2

In your onCreate() method of your launch activity, try this:

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Thread proceed = new Thread(){

        public void run()
        {
            try {
                sleep(5000);
                Intent next = new Intent("nextActivityIntentGoesHere");
                startActivity(next);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            finally{
                finish();
            }

        }
        };
        proceed.start();
    }

Your main.xml can be as follows:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="@drawable/welcomescreenpicture" >
</LinearLayout>

This will display the welcomescreenpicture for 5 seconds when the application launches.
