Click Splash Enter MainActivity

参考​鸿神原文​

1. 默认 AActivity 为闪屏页，BActivity 为主页面
2. ​​Intent.FLAG_ACTIVITY_SINGLE_TOP​​说明

• 当用户点击 HOME 键后，时刻一到并不会自动开启 BActivity，而是后端自动跳转完成
• 当用户进入本 APP 其他页面时，时刻一到自动跳转至 BActivity

public class AActivity extends Activity {

    private Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            Intent it = new Intent(getApplicationContext(), BActivity.class);
            
            // 当用户进入该APP其他页面时,时刻一到自动跳转至B页面
            it.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
            startActivity(it);
            finish();

            handler.removeMessages(-1);
        }
    };

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

        handler.sendMessageDelayed(handler.obtainMessage(-1), 3000);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            handler.sendMessage(handler.obtainMessage(-1));
            finish();
        }
        return super.onTouchEvent(event);
    }
}
