I just wanted to imitate famous games like Angry Birds wherein when you start the game, there are couple of screens, flashing then fading out, then go to another screen, fades out then the main menu comes out. How do i do that? Currently my code is this for the fading in and out. After implementing the code below, surprisingly, it did not animate. Any idea guys?

package com.kfc;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.*;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.AnimationUtils;
import android.widget.LinearLayout;
import android.widget.TextView;

public class Intro extends Activity {
    LinearLayout screen;
    Handler handler = new Handler();
    int i;
    Intent intent;
    TextView tv;
    Animation mAnim;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.introxml);

        screen = (LinearLayout) findViewById(R.id.myintro);


        Animation fade = AnimationUtils.loadAnimation(this, android.R.anim.fade_in);
        fade.setAnimationListener(new AnimationListener() {
            @Override
             public void onAnimationRepeat(Animation animation) {
              // TODO Auto-generated method stub

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

             }
            @Override
             public void onAnimationEnd(Animation animation) {
                startActivity(new Intent(Intro.this, NewKFCActivity.class));
                Intro.this.finish();
                overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
             }

        });
        screen.startAnimation(fade);

    }
}

推荐答案

这可以通过活动动画来完成.

This can be done with activity animations.

在调用startActivity之后，调用

overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);

第一个参数表示您即将启动的活动将淡入，第二个参数指定当前处于前台的活动的淡出动画.

The first argument means that the activity you are about to start is going to fade in, the second argument specifies a fade-out animation for the activity that is currently in the foreground.
