打開手機聯繫人列表，然後選擇一個聯繫人

Question

我使用此代碼打開我的聯繫人列表，然後選擇一個聯繫人以顯示在我的用戶界面中。我可以打開我的聯繫人列表，但是當我點擊任何聯繫人時，程序崩潰。

etphone1.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 

      // Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
      // intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE); 
      // startActivityForResult(intent, 1); 

      Intent pb = new Intent(Intent.ACTION_PICK, 
        ContactsContract.Contacts.CONTENT_URI); 
      startActivityForResult(pb, 1); 

     } 
    }); 

我onActivityForResult：

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    // TODO Auto-generated method stub 
    super.onActivityResult(requestCode, resultCode, data); 

    if (requestCode == 1) { 
     if (resultCode == RESULT_OK) { 
      Uri contactData = data.getData(); 
      Cursor cursor = managedQuery(contactData, null, null, null, 
        null); 
      cursor.moveToFirst(); 

      String number = cursor 
        .getString(cursor 
          .getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      TextView tv; 
      tv = (TextView) findViewById(R.id.tv); 

      tv.setText(number); 

     } 
    } 

} 

的logcat：

Answer 1

以下代碼將3個文本視圖設置爲常用姓名和電話號碼。 設置您的按鈕點擊監聽器 如上所述設置意圖。

@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub 

    intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE); 
    switch (v.getId()) { 
    case R.id.l1: 

     startActivityForResult(intent, 1); 

     break; 
    case R.id.l2: 

     startActivityForResult(intent, 2); 

     break; 
    case R.id.l3: 

     startActivityForResult(intent, 3); 

     break; 

    } 
} 

這是onActivity結果

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    // TODO Auto-generated method stub 
    super.onActivityResult(requestCode, resultCode, data); 

    if (data != null) { 
     Uri uri = data.getData(); 

     if (uri != null) { 
      Cursor c = null; 
      try { 
       c = getContentResolver() 
         .query(uri, 
           new String[] { 
             ContactsContract.CommonDataKinds.Phone.NUMBER, 
             ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME }, 
           null, null, null); 

       if (c != null && c.moveToFirst()) { 
        String number = c.getString(0); 
        String Name = c.getString(1); 

        if (requestCode == 1) { 

         tvname1.setText(Name); 
         tvphone1.setText(number); 

        } else if (requestCode == 2) { 
         tvname2.setText(Name); 
         tvphone2.setText(number); 

        } else if (requestCode == 3) { 
         tvname3.setText(Name); 
         tvphone3.setText(number); 

        } 

       } 
      } finally { 
       if (c != null) { 
        c.close(); 
       } 
      } 
     } 

    } 

} 

Answer 2

不要初始化您的意見onActivityResult可能是問題會因爲你的Textview初始化。在你的onCreate()中聲明它。從下面的方法中刪除TextView初始化，並在onCreate（）中進行初始化並檢查。

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    // TODO Auto-generated method stub 
    super.onActivityResult(requestCode, resultCode, data); 

    if (requestCode == 1) { 
     if (resultCode == RESULT_OK) { 
      Uri contactData = data.getData(); 
      Cursor cursor = managedQuery(contactData, null, null, null, 
        null); 
      cursor.moveToFirst(); 

      String number = cursor 
        .getString(cursor 
          .getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      //TextView tv; 
      //tv = (TextView) findViewById(R.id.tv); //remove this lines. 

      tv.setText(number); 

     } 
    } 

} 

編輯：

試試用下面的代碼：

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

    // this opens the activity. note the Intent.ACTION_GET_CONTENT 
    // and the intent.setType 
    etphone1.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // user BoD suggests using Intent.ACTION_PICK instead of .ACTION_GET_CONTENT to avoid the chooser 
      Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
      // BoD con't: CONTENT_TYPE instead of CONTENT_ITEM_TYPE 
      intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE); 
      startActivityForResult(intent, 1);     
     } 
    }); 
} 

現在，只要用戶選擇的聯繫人（也可能選擇幾個電話號碼之一）你可以用正常方式檢索數據：

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (data != null) { 
     Uri uri = data.getData(); 

     if (uri != null) { 
      Cursor c = null; 
      try { 
       c = getContentResolver().query(uri, new String[]{ 
          ContactsContract.CommonDataKinds.Phone.NUMBER, 
       ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME }, 
         null, null, null); 

       if (c != null && c.moveToFirst()) { 
        String number = c.getString(0); 
        String Name=c.getString(1); 
        Toast.makeText(this, number + Name, Toast.LENGTH_LONG).show();  
       } 
      } finally { 
       if (c != null) { 
        c.close(); 
       } 
      } 
     } 
    } 
}
