如何使活动模糊然后随着新活动消失？

Question

I have a slpash screen which has one image I want to make the image or activity blur before the next activity gets called.

I tried to use fade_in fade_out anim but its not working.

Tried code given in this accepted answer : Android Studio fading splash into main

splashScreen

public class SplashScreen extends Activity {

    private Thread mSplashThread;

    @Override

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash_layout);
        final SplashScreen sPlashScreen = this;

        mSplashThread =  new Thread(){
            @Override
            public void run(){
                try {
                    synchronized(this){
                        wait(3000);
                    }
                }
                catch(InterruptedException ex){
                }

                finish();

                Intent intent = new Intent();
                intent.setClass(sPlashScreen,LoginActivity.class);
                startActivity(intent);
                overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
            }
        };

        mSplashThread.start();
    }

    @Override
    public boolean onTouchEvent(MotionEvent evt)
    {
        if(evt.getAction() == MotionEvent.ACTION_DOWN)
        {
            synchronized(mSplashThread){
                mSplashThread.notifyAll();
            }
        }
        return true;
    }
}

Fade_in :

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:fromAlpha="0.0" android:toAlpha="1.0"
    android:duration="500" />

Fade_out :

   <?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:fromAlpha="1.0" android:toAlpha="0.0"
    android:fillAfter="true"
    android:duration="500" />

What Can I do for blur animation? I want the slpash activity to look blur before the another activity starts.

Please help.Thank you..

Answer 1

If overridePendingTransition doesn't work as you want for fade_in and fade_out. You can make a workaround. before navigating, make a animation for your app container to Blur, using a animation library like: https://github.com/2359media/EasyAndroidAnimations or https://github.com/daimajia/AndroidViewAnimations And an animation to fade in the content of the next activty, and use activity.overridePendingTransition(NO_ANIMATION, NO_ANIMATION);

Note: this is not something I tried, but it should work

Answer 2

You can add one overlay in splash_layout as shown below to have the dim effect. and make it visible before starting the new activity.

<View
    android:id="@+id/overlay_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#A0000000"
    android:visibility="gone" />

Hope this helps.
