Question

我正在尝试设置一个以编程方式创建的按钮，以便在单击时打开一个新活动并使用putExtra但是Activity在打开后甚至不会保持打开状态，它会保持1秒钟然后崩溃。

按钮代码：

blogs[i].setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    Log.e("button", "blog clicked");
                    Intent i = new Intent(getSherlockActivity(), Soundcloud.class);
                    startActivity(i);
                }
            });

新班级：

public class Soundcloud extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    //this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);
    //setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    Log.e("activity", "in activity");
    setContentView(R.layout.soundcloud);

}
}

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="vertical" >
</LinearLayout>

manifest.xml：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.********"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />

<permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.INTERNET" />

<permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <activity
        android:name="com.*****.***.MainActivity"
        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="com.*****.***.Soundcloud"
        android:label="Blog" >
    </activity>

</application>
</manifest>

logcat的：

07-24 22:27:22.310: E/pass 2.2(24015): blogs - connection success 
07-24 22:27:23.990: E/button(24015): blog clicked
07-24 22:27:24.280: E/activity(24015): in activity
07-24 22:27:25.080: W/dalvikvm(24015): threadid=1: thread exiting with uncaught exception (group=0x40f21438)

这应该完成它

 blogs[i].setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    Log.e("button", "blog clicked");
                    Intent i = new Intent(getActivity(), Soundcloud.class);
                    getActivity().startActivity(i);
                }
            });
