I am new in Android Development. I have been trying to figure out how to display a screen in android studio only for 5 seconds and then get transfered into a new activity.
For example: Activity A -> Activity B (Shown for 5 seconds) -> Activity C
Also I want to make sure that when a user clicks on the back button while he is in Activity B nothing happens (It doesnt go back to Activity A).
What is the easiest way to do that? I know I have to use Intent.
try this. I have commented it out, but if you have any questions about it feel free to ask.
public class ClassB extends AppCompatActivity {
//Handler allows you to send and process Runnable Objects (Classes in this case)
private Handler mHandler = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_classb);
//postDelayed method, Causes the Runnable r (in this case Class B) to be added to the message queue, to be run
// after the specified amount of time elapses.
mHandler.postDelayed(new Runnable() {
@Override
public void run() {
//Create a new Intent to go from Class B to Class C and start the new Activity.
Intent intent = new Intent(ClassB.this, ClassC.class);
startActivity(intent);
finish()
}
//Here after the comma you specify the amount of time you want the screen to be delayed. 5000 is for 5 seconds.
}, 5000);
}
//Override onBackPressed method and give it no functionality. This way when the user clicks the back button he will not go back.
public void onBackPressed() {
} }
In Kotlin you can do:
Handler().postDelayed({
// Start activity
startActivity(Intent(this, YourTargetActivity::class.java))
// terminate this activity(optional)
finish()
}, 5000)
