Question

我正在尝试显示来自通话记录的号码。我的应用程序中有一个按钮，用于将用户重定向到电话的日志活动，当用户选择联系人时，它将显示在主要活动的文本视图中。我已经在清单中添加了对调用日志读取的权限，但是我收到了这个错误：

代码：

button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View arg0) {
                    // TODO Auto-generated method stub
                    Intent intent = new Intent(Intent.ACTION_PICK);
                    intent.setData(android.provider.CallLog.Calls.CONTENT_URI);
                    startActivityForResult(intent, 0);
                }
            });



    public void onActivityResult(int requestCode, int resultCode, Intent intent)
    {
        String[] callLogFields = { android.provider.CallLog.Calls._ID,
                android.provider.CallLog.Calls.NUMBER,
                android.provider.CallLog.Calls.CACHED_NAME };
        String phoneNumber="Not Selected Yet" ;
        Cursor c =  managedQuery(intent.getData(), callLogFields, null, null, null);
        if(c!=null && c.moveToFirst())
        {
    phoneNumber=c.getString(c.getColumnIndex(android.provider.CallLog.Calls.NUMBER));
        }
        c.close();
        textview.setText(phoneNumber);
    }

这是因为你根本不能 Android没有提供ACTION_PICK呼叫日志的方法但您可以使用此解决方法在应用上显示列表。

        String[] strFields = { android.provider.CallLog.Calls._ID, android.provider.CallLog.Calls.NUMBER,
                android.provider.CallLog.Calls.CACHED_NAME, };
        String strOrder = android.provider.CallLog.Calls.DATE + " DESC";
        final Cursor cursorCall = getActivity().getContentResolver().query(android.provider.CallLog.Calls.CONTENT_URI, strFields, null, null,
                strOrder);

        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("Select recent contact");
        android.content.DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialogInterface, int item) {
                cursorCall.moveToPosition(item);
                Toast.makeText(getActivity(), cursorCall.getString(cursorCall.getColumnIndex(android.provider.CallLog.Calls.NUMBER)),
                        Toast.LENGTH_LONG).show();
                cursorCall.close();
                return;
            }
        };
        builder.setCursor(cursorCall, listener, android.provider.CallLog.Calls.CACHED_NAME);
        builder.create().show();

这需要以下许可：

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

使用intent从呼叫日志中显示特定联系人
