无法使用动画android / java开始活动

Question

The animation on the first activity does not work when I use startActivity and I don't know it's strange.

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        getSupportActionBar().hide();

        ImageView img = (ImageView) findViewById(R.id.splash);
        img.animate().scaleX(0.6f).scaleY(0.6f).rotation(1080f).setDuration(2000);
        Intent intent = new Intent(getApplicationContext(), NextActivity.class);
        startActivity(intent);
    }
}

Answer 1

Use this.

    private Handler handlerImage;
    private Runnable runnableImage;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    getSupportActionBar().hide();

    ImageView img= (ImageView) findViewById(R.id.splash);
    img.animate().scaleX(0.6f).scaleY(0.6f).rotation(1080f).setDuration(2000);
    handlerImage = new Handler();
    runnableImage = new Runnable() {
        @Override
        public void run() {
            Intent intent=new Intent(getApplicationContext(),NextActivity.class);
            startActivity(intent);
        }
    };
    handlerImage.postDelayed(runnableImage, 3000);

}



@Override
protected void onDestroy() {
    super.onDestroy();
    if (handlerImage != null) {
        handlerImage.removeCallbacks(runnableImage);
    }

}

I hope you are trying to show a scale and rotation animation of your APP logo for sometime and then trying to launch Another Activity.

Since you are starting Another activity ,Before Starting Animation on the Imageview, ActivityManager will switch to the Next Animation, and hence you are not able to see the Animation, Solution is to set an Animationlistner to the ViewPropertyAnimator object given to ImageView and Start the main Activity on onAnimationEnd() callback.

code snippet is given below:

    img.animate().scaleX(0.6f).scaleY(0.6f).rotation(1080f).setDuration(2000).setListener(new AnimatorListener() {

        @Override
        public void onAnimationStart(Animator animation) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onAnimationRepeat(Animator animation) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onAnimationEnd(Animator animation) {
            Intent intent=new Intent(getApplicationContext(),NextActivity.class);
            startActivity(intent);

        }

        @Override
        public void onAnimationCancel(Animator animation) {
            // TODO Auto-generated method stub

        }
    });

Answer 3

Check this,

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

@Zakaria Ait Ouchrif,

You can use the method of Activity overridePendingTransition() with two xml of in and out Animation.

You can define simple transition animations in an XML resource file.

Also you can refer this tutorial for same.
