Android – get / set the sharedpreference global value

Hi, I have a class (mycustomform. XML) that I use as the loginform of the user. Now I want to use SharedPreferences to save and load the value in the user name (EditText) from loginform, but I don't know how to set the username value saved by SharedPreferences to EditText in loginform (mycustomform. XML)

I want to save the value in onpause in my main.xml and load the value through oncreate in the class mycustomform.xml

Usually I want to use global SharedPreferences

How does this look? Can someone help me get on track?

It is thinking of the following main.xml:

public class AndroidLogin extends Activity implements OnClickListener {

@Override     
protected void onPause() { 
   super.onPause();  
     Editor e = mPrefs.edit();
     e.putString(USERNM, username);
     e.commit();
}
}
@H_502_18@
代码MyCustomForm(LoginForm)：

public class MyCustomForm extends Dialog {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(com.sencide.R.layout.inlogdialog);

    EditText userTest = (EditText)findViewById(R.id.txtUserName);
    userTest.setText(USERNM);
}
}

解决方法:
你可以这样做：

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(YouActivity.this);

String servername = settings.getString("sharedPreferencesKey", "defaultValue");
server.setText(servername);  // EditText
@H_502_18@
你存储这样的数据：

SharedPreferences.Editor editor = settings.edit();
editor.putString("server", "serverName");
@H_502_18@
编辑：
这段代码应该为您解决问题：

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
String servername = settings.getString("sharedPreferencesKey", "defaultValue");
@H_502_18@
