How do I show a splash screen in Android?

Question

I want to show a splash screen when my app loads up, this is my Java code:

ImageView splash = (ImageView) this.findViewById(R.id.splashscreen);

splash.postDelayed(new Runnable(){
    splash.setVisibility(View.GONE);
}, 3000);

But I am getting the error "cannot resolve symbol" on the postDelayed() call. Also I get the "unexpected token" for

}, 3000);

Finally, this is my layout:

<TextView
    android:text="@string/hello_world"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<ImageView
    android:id="@+id/splashscreen"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:src="@drawable/splash"
    android:layout_gravity="center"/>

Answer 1

You can do as follows:

private static final int SPLASH_TIME_OUT = 2000;
private static final Handler mHandler = new Handler();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);

    mHandler.postDelayed(new Runnable() {

        @Override
        public void run() {

                startActivity(new Intent(getApplicationContext(), YourActivity.class)); 
                finish();   
        }
    }, SPLASH_TIME_OUT);    
}

Here activity_splash.xml is your splash Activity layout and YourActivity is the Activity you're going to next.

Answer 2

private ImageView splash;


splash = (ImageView)findViewById(R.id.splashscreen);
new Handler().postDelayed(new Runnable(){
    @Override
public void run() {
        splash.setVisibility(View.GONE);
    }
}, 3000);

Try this.
