Android从通话记录屏幕中提取条目 [英] Android pick up entry from call history screen

问题描述

使用下面从互联网获得的代码，我已经可以进入手机的通话记录屏幕。

I have been able to reach the call logs screen of my phone using the below code i got from internet. Is it possible to pick up the entry details, say number, time of call etc of single entry with on click ?

Intent showCallLog = new Intent();
    showCallLog.setAction(Intent.ACTION_VIEW);
    showCallLog.setType(CallLog.Calls.CONTENT_TYPE);
    startActivity(showCallLog);

推荐答案

您不能使用意图选择单个条目

You can not use a intent to pick a single entry from logs.

但是您可以从db获取所有信息，并将它们显示在对话框列表中，然后选择任意一个联系人您想要的。

But you can get all info from db and show them into a dialog list and then select any contact you want.

在下面检查代码的工作方式。

注意：在清单中添加权限，如果您的 OS是6.0或更高版本，则获得运行时权限如何 此处。

Note: Add permission in manifest and If your OS is 6.0 or greater then get runtime permission from user how here.

<使用权限android：name = android.permission.READ_CALL_LOG />

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button ContactPickBtn = (Button) findViewById(R.id.btnPick);
        ContactPickBtn.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                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";
                // Make you have call logs permissions
                // if your os is 6.0 get call log permission at runtime.
                final Cursor cursorCall = getContentResolver().query(
                        android.provider.CallLog.Calls.CONTENT_URI, strFields,
                        null, null, strOrder);

                AlertDialog.Builder builder = new AlertDialog.Builder(
                        MainActivity.this);
                builder.setTitle("Pick a contact");
                android.content.DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialogInterface,
                                        int item) {
                        cursorCall.moveToPosition(item);
                        Toast.makeText(
                                MainActivity.this,
                                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();
            }
        });
    }
}
