联系选择器在对话框中 [英] Contact picker in a dialog

问题描述

我的Android应用程序中有一个自定义对话框。我想在此对话框中有一个字段用于从联系人中选择一个电话号码。
此示例描述了这样的片段。但是，对于这个例子，联系人选择器是在活动内部创建的，如果没有活动（对话框的情况），我不知道如何执行此操作。

解决方案

此代码解决了问题。

  public class ContactFieldActivity extends Activity {
 private static final int PICK_NUMBER = 1; 
 
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.field_contact）; 
 
按钮btnContacts =（Button）findViewById（R.id.btn_contacts）; 
 
 btnContacts.setOnClickListener（new OnClickListener（）{
 
 public void onClick（View arg0）{
 Intent intent = new Intent（Intent.ACTION_PICK，Phones.CONTENT_URI ）; 
 startActivityForResult（intent，PICK_NUMBER）; 
}}）; 
} 
 
 @Override 
 protected void onActivityResult（int requestCode，int resultCode，Intent data）{
 super.onActivityResult（requestCode，resultCode，data）; 
 
 switch（requestCode）{
 case（PICK_NUMBER）：
 if（resultCode == Activity.RESULT_OK）{
 Uri contactData = data.getData（）; 
 Cursor c = managedQuery（contactData，null，null，null，null）; 
 if（c.moveToFirst（））{
 String number = c.getString（c.getColumnIndexOrThrow（Phones.NUMBER））; 
 EditText edit =（EditText）findViewById（R.id.editNumber）; 
 edit.setText（number）; 
} 
} 
 break; 
} 
} 
  

}

I have a custom dialog in my android application. I want to have in this dialog a field for choosing a phone number from contacts. This example describes such snippet. However for this example contact picker is created inside an activity and I do not know how to do this if I do not have activity (in case of dialog)

解决方案

This code solves the problem.

  public class ContactFieldActivity extends Activity {
private static final int PICK_NUMBER = 1;

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

    Button btnContacts = (Button)findViewById(R.id.btn_contacts);

    btnContacts.setOnClickListener(new OnClickListener() {  

        public void onClick(View arg0) {  
            Intent intent = new Intent(Intent.ACTION_PICK, Phones.CONTENT_URI);
            startActivityForResult(intent, PICK_NUMBER);
        }});
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {  
         case (PICK_NUMBER):  
             if (resultCode == Activity.RESULT_OK) {  
                 Uri contactData = data.getData();  
                 Cursor c = managedQuery(contactData, null, null, null, null);  
                 if (c.moveToFirst()) {  
                     String number = c.getString(c.getColumnIndexOrThrow(Phones.NUMBER));
                     EditText edit = (EditText)findViewById(R.id.editNumber);
                     edit.setText(number);  
                 }  
             }  
             break;  
     }      
}   

}
