Question

当我运行应用程序时，SplashScreen在屏幕上闪烁一小秒，然后完全消失3秒钟。完成3秒后，MainActivity启动。问题是如何在没有消失的情况下显示我的启动画面？

public class SplashScreen extends Activity {
private static int SPLASH_TIME_OUT = 3000;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash_screen);

    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            startActivity(new Intent(SplashScreen.this, MainActivity.class));

        }
    }, SPLASH_TIME_OUT);
    SplashScreen.this.finish();
}

@Override
public void onBackPressed() {
    SplashScreen.this.finish();
    super.onBackPressed();
}}

清单文件

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity android:name="com.simbotix.guardianonthego.SplashScreen" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name="com.simbotix.guardianonthego.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
    </application>

Answer 1

更改此

 new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            startActivity(new Intent(SplashScreen.this, MainActivity.class));

        }
    }, SPLASH_TIME_OUT);
    SplashScreen.this.finish();

到

new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
             startActivity(new Intent(SplashScreen.this, MainActivity.class));
              SplashScreen.this.finish();
        }
    }, SPLASH_TIME_OUT);

也无需在onBackPressed

中完成活动

@Override
public void onBackPressed() {
    SplashScreen.this.finish(); // Remove this
    super.onBackPressed();
}

Answer 2

       new Handler().postDelayed(new Runnable() {    
        @Override
        public void run() {
            startActivity(new Intent(SplashScreen.this, MainActivity.class));
            SplashScreen.this.finish();

        }
    }, SPLASH_TIME_OUT);

SplashScreen.this.finish（）;代码行完成你的SplashActivity，你需要在3秒后执行此操作，这就是为什么它在处理程序线程中并在3秒后执行。

Answer 3

在开始SplashScreen之前，只是不要完成MainActivity。只需从SplashScreen.this.finish();课程中删除SplashScreen行即可。

Answer 4

 public void run() {
                startActivity(new Intent(SplashScreen.this, MainActivity.class));
                finish()
            }
 }, SPLASH_TIME_OUT);

而不是

public void run() {
            startActivity(new Intent(SplashScreen.this, MainActivity.class));

        }
    }, SPLASH_TIME_OUT);
    SplashScreen.this.finish();

Answer 5

快速修复：

删除

SplashScreen.this.finish();

改变之类，

public void run() {
        startActivity(new Intent(SplashScreen.this, MainActivity.class));
        finish();
    }

启动画面不在android中显示
