Question

所以我试图使用Intents切换视图，我之前已经能够正常工作但现在它只是保持关闭，这也是通过菜单按钮，继承我的菜单代码：

public boolean onCreateOptionsMenu(android.view.Menu menu) {
    super.onCreateOptionsMenu(menu);
    MenuInflater blowUp = getMenuInflater();
    blowUp.inflate(R.menu.menu, menu);
    return true;
}
public boolean onOptionsItemSelected(MenuItem item){
    switch(item.getItemId()){
    case R.id.stats:
            Intent i = new Intent("com.mittereder.rockpaper.STATS");
            startActivity(i);
        break;
    }
    return false;
}

这是我的菜单，其中包含该项目：

    <?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/stats"
        android:alphabeticShortcut="s"
        android:title="Stats"/>

</menu>

然后这是我的清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mittereder.rockpaper"
    android:versionCode="2"
    android:versionName="1.2" >

    <uses-sdk android:minSdkVersion="8" />

    <application
        android:icon="@drawable/stop"
        android:label="@string/app_name" >
        <activity
            android:name=".start"
            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=".stats"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="com.mittereder.rockpaper.STATS" />

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

</manifest>

我一遍又一遍地查看我的代码，我不知道我错过了什么。

logcat的：

Answer 1

看起来你的Start Activity会覆盖onPause并且不会调用超类。在启动stat活动之前，会在启动活动上调用onPause。

我的Intent不适用于android
