问题:

回答1:

try android:theme="@android:style/Theme.NoTitleBar.Fullscreen" in the activity tag in your manifest file.

Edit:

Use requestWindowFeature(Window.FEATURE_NO_TITLE) in your onCreate() before you call setContentView () to set programmatically.

I have found solution.

we can out following code in activity from which we are creating and starting Intent

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Intent scanIntent = new Intent(this, SecondActivity.class);
startActivity(scanIntent);

By this it will hide status bar first then it will move to next activity.

Above code will require only when you are using single instance for second activity. else you can apply solution given by Vineet Shukla
