White screen is displayed while switching between Activities

Question

When I move from one Activity to another Activity, a white screen is displayed for 2 seconds. I am using this code:

Intent intent = new Intent(this, SecondActivity.class);
startActivity(intent);

How can I resolve this issue?

Answer 1

Create a Theme like this:

<style name="YourTheme" parent="YourParentTheme">
    <item name="android:windowDisablePreview">true</item>
</style>

Apply this theme to your second activity

Answer 2

If your activity contains more complex layouts, do not use finish() after setting flag. Use FLAG_ACTIVITY_CLEAR_TOP and _TASK instead and it will solve your problem.This worked for me perfectly

Intent intent = new Intent(this, SecondActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.l̥FLAG_ACTIVITY_CLEAR_TOP ); startActivity(intent);

or use simply like below

Intent intent = new Intent(this, SecondActivity.class); startActivity(intent);
