Question

如何在启动应用程序时显示启动屏幕，我尝试向应用程序添加启动屏幕，但不适用于我。这是我的代码

SplashActivity

import { shallowEqual, useSelector } from 'react-redux'

// later
const selectedData = useSelector(selectorReturningObject, shallowEqual)

清单

public class SplashActivity extends AppCompatActivity {

int SPLASH_TIME = 3000; //This is 3 seconds
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splach);

    //Code to start timer and take action after the timer ends
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            //Do any action here. Now we are moving to next page
            Intent mySuperIntent = new Intent(SplashActivity.this, MainActivity.class);
            startActivity(mySuperIntent);

            //This 'finish()' is for exiting the app when back button pressed from Home page which is ActivityHome
            finish();
        }
    }, SPLASH_TIME);
}
}

Answer 1

您的启动程序必须是启动程序：

<activity android:name=".MainActivity" />
<activity android:name=".SplashActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

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

Answer 2

您应该将这部分放在开始活动的标签中。

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

例如：

<activity android:name=".StartActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

希望它会对您有所帮助。
