Question

我试图在3秒钟后自动显示另一个活动，但我在第二个屏幕上出现了一个奇怪的闪烁。这就是我得到的： https://i.gyazo.com/bfd2c003b2bdd3a639a6db5f658da062.gif

我的代码：

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ImageView image = (ImageView) findViewById(R.id.imageView1);
    TextView text = (TextView) findViewById(R.id.text2);
    Typeface cfont = Typeface.createFromAsset(getAssets(), "fonts/KeeponTruckin.ttf");
    text.setTypeface(cfont);
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        public void run() {
            // TODO: Your application init goes here.
            Intent intent = new Intent(MainActivity.this, SecondActivity.class);
            MainActivity.this.startActivity(intent);
            MainActivity.this.finish();
        }
    }, 3000);
}

感谢您的帮助。

我不知道为什么，maby模拟器android制作它。您可以为plash_screen活动设置转换（例如：淡出）以获得最佳UX。将folow代码插入代码

enum Direction:String {     
    case N = "n"
    case NE = "ne"
    case E = "e"
    case SE = "se"
    case S = "s"
    case SW = "sw"
    case W = "w"
    case NW = "nw"
}

enum Action: String {
    case Idle = "droid"
    case Move = "droid_move"
}

func spriteFramesDroid(direction:Direction, action:Action) -> String {
    return "\(action.rawValue)_\(direction.rawValue)"

}

fade_in.xml（推送到Intent intent = new Intent(MainActivity.this, SecondActivity.class); MainActivity.this.startActivity(intent); overridePendingTransition(R.anim.fade_in, R.anim.fade_out);文件夹）

anim

fade_out.xml

<?xml version="1.0" encoding="utf-8"?>
              <?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" />

如果您不想要进行动画转换，请将您的意图更改为：

Intent intent = new Intent(MainActivity.this, SecondActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
MainActivity.this.startActivity(intent);
MainActivity.this.finish();

如果您想要淡入/淡出效果，请在开始活动前调用以下内容：

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

尝试从一个活动转移到另一个活动时屏幕闪烁
