扩展LockPatternActivity时发生错误 [英] Errors occured when extending LockPatternActivity

问题描述

在我的申请，我想扩展LockPatternActivity库类：

Inside my application, I wanna extends LockPatternActivity library class :

的https：//$c$c.google.com/p/android -lockpattern /

import com.haibison.android.lockpattern.LockPatternActivity;
import com.haibison.android.lockpattern.R;
import com.haibison.android.lockpattern.*;
public class ExtendPatternActivity extends LockPatternActivity{

}

它们使用lockpattern类：

The class which use lockpattern :

   public class PatternSetter extends Activity{


Context context = this;
final int REQ_CREATE_PATTERN = 1;


@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    this.setContentView(R.layout.pattern_setter);

     Settings.Security.setAutoSavePattern(this, true);

 Intent intent = new Intent(LockPatternActivity.ACTION_CREATE_PATTERN, null, this, ExtendPatternActivity.class);
     this.startActivityForResult(intent, REQ_CREATE_PATTERN);



}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
    case REQ_CREATE_PATTERN: {
        if (resultCode == RESULT_OK) {
            char[] pattern = data.getCharArrayExtra(
                    LockPatternActivity.EXTRA_PATTERN);
                    Intent intent = new Intent(context, MainTheftActivity.class);
                    context.startActivity(intent);


}

但这个错误的错误：

But this errors error :

似乎ExtendPatternActivity不能在lockpattern库正确加载的资源？
我应该如何在图书馆我的应用程序加载的资源？
非常感谢..

It seems that ExtendPatternActivity cant load the resources in lockpattern library properly? How should I load resources in the library to my application? Thanks a lot..

推荐答案

原因这些错误是，我忘了一些属性在Android清单添加到我的活动。
它应该是：

The reason for these errors is that I forgot the add some attributes to my activity in the android manifest. It should be :

    <activity android:name="ExtendPatternActivity"
           android:configChanges="orientation|screenSize|keyboard|keyboardHidden"
           android:screenOrientation="user"
            android:theme="@style/Alp.42447968.Theme.Dark" 
            >   

   </activity>

而不是：

    <activity android:name="ExtendPatternActivity">   

   </activity>
