You should update ui on the ui thread. Use runonUithread.
runOnUiThread(new Runnable() {
@Override
public void run() {
// set image to imageview here
// ui should be updated on the ui thread.
// you cannot update ui from a background thread
}
});
But i would suggest you to use a handler.
public class Splash extends Activity {
//stopping splash screen starting home activity.
private static final int STOPSPLASH = 0;
//time duration in millisecond for which your splash screen should visible to
//user. here i have taken half second
private static final long SPLASHTIME = 500;
//handler for splash screen
private Handler splashHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case STOPSPLASH:
//Generating and Starting new intent on splash time out
Intent intent = new Intent(Splash.this,
MainActivity.class);
startActivity(intent);
Splash.this.finish();
break;
}
super.handleMessage(msg);
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
//Generating message and sending it to splash handle
Message msg = new Message();
msg.what = STOPSPLASH;
splashHandler.sendMessageDelayed(msg, SPLASHTIME);
}
}
splash.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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/mydrawable">
// have a imageview and set background to imageview
</RelativeLayout>
Using handlers and postdelayed
public class Splash extends Activity {
private static final int SPLASH_TIME = 2 * 1000;// 3 seconds
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
ImageView iv= (ImageView) findViewById(R.id.imageView1);
iv.setBackgroundResource(R.drawable.afor);
try {
new Handler().postDelayed(new Runnable() {
public void run() {
Intent intent = new Intent(Splash.this,
MainActivity.class);
startActivity(intent);
Splash.this.finish();
}
}, SPLASH_TIME);
} catch(Exception e)
{
e.printStacktrace();
}
}
@Override
public void onBackPressed() {
this.finish();
super.onBackPressed();
}
}
splash.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
