Android6.0撥打電話時的權限問題

首先在AndroidMenifest文件里加上這個權限： <uses-permission android:name="android.permission.CALL_PHONE" />

1.若是是直接跳轉到撥號盤,是不存在權限管制的問題的. 2.若是是直接撥打電話,會存在權限動態獲取的問題. 解決的代碼以下:

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                    //沒有權限,申請受權
                    if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CALL_PHONE)) {
                        //若是app以前請求過該權限,被用戶拒絕, 這個方法就會返回true.
                        // 若是用戶以前拒絕權限的時候勾選了對話框中」Don’t ask again」的選項,那麼這個方法會返回false.
                        // 若是設備策略禁止應用擁有這條權限, 這個方法也返回false.
                        // 彈窗須要解釋爲什麼須要該權限，再次請求受權
                        Util.showToast(MyRevationDetailActivity.this, getResources().getString(R.string.call_phone_authority_tv));
                        //跳轉到該應用的設置界面,讓用戶手動受權
                        Intent intentSet = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                        Uri uri = Uri.fromParts("package", getPackageName(), null);
                        intentSet.setData(uri);
                        startActivity(intentSet);
                    } else {
                        //直接請求受權
                        /*
                        在Fragment中申請權限，不要使用ActivityCompat.requestPermissions,
                        直接使用Fragment的requestPermissions方法，不然會回調到Activity的onRequestPermissionsResult
                         */
                        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, Util.HTTP_CALL_PHONE_REQUEST);
                    }
                    // TODO: Consider calling
                    //    ActivityCompat#requestPermissions
                    // here to request the missing permissions, and then overriding
                    //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                    //                                          int[] grantResults)
                    // to handle the case where the user grants the permission. See the documentation
                    // for ActivityCompat#requestPermissions for more details.
                    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, Util.HTTP_CALL_PHONE_REQUEST);
                } else {
                    //在這裏直接撥打電話
                    Intent intent = new Intent(Intent.ACTION_CALL);
                    Uri data = Uri.parse("tel:" + "電話號碼");
                    intent.setData(data);
                    startActivity(intent);
                }

@Override
	public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
		super.onRequestPermissionsResult(requestCode, permissions, grantResults);
                //requestCode 是一個標識,
		if (requestCode == Util.MY_PERMISSIONS_REQUEST_CALL_PHONE) {
			if (grantResults[0] == PackageManager.PERMISSION_GRANTED)
			{
                                 //獲取到權限以後,進行下一步操做
				startTakePhoto();
			} else {
				//跳轉到該應用的設置界面,讓用戶手動受權
				Intent intentSet = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
