Android Splash屏幕无法加载其他活动

Question

以下是我的Android启动画面活动的代码。

当它尝试加载另一个活动时，应用程序在Android 4.0和4.1上崩溃。

我不知道造成这种情况的原因是什么，因为当它崩溃时，它不会记录任何错误。

有没有人遇到过像这样的事情？

修改：AndroidManifest.xml

我认为，由于Android版本不会出现崩溃，因此问题可能是由于OpenGL版本不兼容造成的。

我认为您无法在AndroidManifest.xml.plz中添加启动画面检查

   import android.app.Activity;
   import android.content.Intent;
   import android.os.Bundle;


   public class Splash extends Activity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
          setContentView(R.layout.splash);

    Thread logoTimer = new Thread() {
        public void run() {
            try {
                int logoTimer = 0;
                while (logoTimer < 500) {
                    sleep(100);
                    logoTimer = logoTimer + 100;
                }

                Intent newIntent = new Intent(Splash.this,      MainActivity.class);
                startActivity(newIntent);
            } catch(InterruptedException e) {
                e.printStackTrace();
            } finally {
                finish();
            }
        }
    };
    logoTimer.start();
}

}

Android Manifest.xml中的

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

您可以将以下活动与一些简单内容一起使用。注入布局（见下文）并在布局文件中注册一个onclick-listener（方法＆＃34; forward＆＃34;）。在此方法中，您可以调用下一个活动：

public class SplashScreen extends Activity{

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

    public void forward(View v){
        startActivity(new Intent(this, MainActivity.class), 0);
    }
}

splashscreen.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
    <ImageView
        android:id="@+id/splashscreen"
        android:onClick="forward"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:src="@drawable/ic_launcher" />
</LinearLayout>

添加AndroidManifest.xml：

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >
    <activity
        android:name=".SplashScreen"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".MainActivity" />
</application>

课程＆＃34; MainActivity＆＃34;代表您的主要活动和课程＆＃34; SplashScreen＆＃34;代表一个简单的启动画面。

我希望这会对你有所帮助:)。

我看到的问题是，在调用activity标记时，你仍然在name属性中使用.activity 即你使用android:name=".activity.MainActivity" 对于启动画面活动和主要活动，我们都不是android:name=".MainActivity"。
