无法删除短信

Question

我想删除短信。

String URI = "content://sms/inbox"; 
Cursor cursor = getContentResolver().query(Uri.parse(URI), null,null, null, null); 
String[] _id = new String[cursor.getCount()]; 
String[] thread_id = new String[cursor.getCount()]; 
if (cursor.moveToFirst()) { 
    for (int i = 0; i < cursor.getCount(); i++) { 
     try { 
      _id[i] = cursor.getString(cursor.getColumnIndexOrThrow("_id")).toString(); 
      thread_id[i] = cursor.getString(cursor.getColumnIndexOrThrow("thread_id")).toString(); 
     } catch (IllegalArgumentException e) { 
      Log.d(TAG, e.toString()); 
     } 
    } 
} 
final String id = _id[0]; // for debugging deleting the first msg 
final String tid = thread_id[0]; // for debugging deleting the first msg 
((Button) findViewById(R.id.delete)).setOnClickListener(new View.OnClickListener() { 
    public void onClick(View v) { 
      Log.d(TAG, "id="+id+",tid="+tid); 
      getContentResolver().delete(Uri.parse(URI),"_id=" + id + " and thread_id=" + tid,new String[] { String.valueOf(id),String.valueOf(tid) }); 
      Toast.makeText(getApplicationContext(), "SMS DELETED. RESTARTING ACTIVITY", Toast.LENGTH_LONG); 
      Intent i = getApplicationContext().getPackageManager().getLaunchIntentForPackage(getApplicationContext().getPackageName()); 
      i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP| Intent.FLAG_ACTIVITY_NEW_TASK); 
      startActivity(i); 
    } 
}); 

它抛出一个异常：在删除删除

抛出异常。我有以下我的清单：

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

我试图改变的URL content://sms为删除。不工作。给出以下例外：

有人可以看看这个，并告诉问题是什么？

Answer 1

我想你实际上需要的是：

getContentResolver().delete(Uri.parse(URI),"_id=? and thread_id=?",new String[] { String.valueOf(id),String.valueOf(tid) }); 

它看起来像delete（）的使用准备好的语句，这意味着，因为它们是在第三过去了，你就不会通过IDS在声明中字符串论据。

Answer 2

MyActivity.java

private static final String ADDRESS_COLUMN_NAME = "address"; 
    private static final String DATE_COLUMN_NAME = "date"; 
    private static final String BODY_COLUMN_NAME = "body"; 
    private static final String ID_COLUMN_NAME = "_id"; 

    (...) 

    // Defines selection criteria for the rows you want to delete 
    String mSelectionClause = ADDRESS_COLUMN_NAME + " = ? AND " + BODY_COLUMN_NAME + " = ? AND " + DATE_COLUMN_NAME + " = ?"; 

    String[] mSelectionArgs = new String[3]; 
    mSelectionArgs[0] = currentSms.getAddress(); 
    mSelectionArgs[1] = currentSms.getMsg(); 
    mSelectionArgs[2] = currentSms.getDate().toString(); 

    ContentResolver contentResolver = getContentResolver(); 

    // Delete from database 
    int rowsDeleted = 0; 
    rowsDeleted = contentResolver.delete(
      Uri.parse("content://sms"), // the sms content URI 
      mSelectionClause,     // the column to select on 
      mSelectionArgs      // the value to compare to 
    ); 

    if (rowsDeleted > 0) { 
     Log.d(TAG, "Success!"); 
    } else { 
     Log.d(TAG, "Delete sms UNSUCCESSFULL!!!"); 
    } 

注意：不要忘记检查权限读，写短信。和版本> KitKat该应用程序必须是短信的默认应用程序。
