Question

我正在使用具有OS Android 5.1.1的Motorola G3设备。

当我尝试从图库中选择一张图片并将其设置为ImageView时，我会遇到异常。以下是我的代码：

<form  method='post'>

                <input name="username" type="text" placeholder="Username" required="">

      <input name="steamid" type="text" placeholder="SteamID64" required="">

                </div>


            <input type="submit" value="SEND APP" name="submit21" />
          </form>
      <?php 
      if (isset($_POST['submit21'])) {
    echo "<h4>Your apply has been sended successfully, check your mail within 1 day to 7 days to get your answer from the staff team.</h4>";
    header("refresh:5;url=../apply/steamauth/logout.php");
$_POST['username']      = $username;
$_POST['steamid']       = $steamid2;
$_POST['horarytime']    = $horarytime;

$_POST['donated']       = $hasdonated;
$_POST['age']         = $age;

$to = "noreply@vanityrp.site.nfoservers.com";

";

// Always set content-type when sending HTML email
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

// More headers
$headers .= 'From: noreply@vanityrp.site.nfoservers.com' . "\r\n";

mail($to,$subject,$message,$headers);
      }
      ?>

我调试了代码，并且知道URI正常运行，问题是初始化Bitmap对象。

在这里，我有一个例外：

请有人帮我解决这个问题：

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        String selectedImageUri = getImageFromChooser(requestCode, resultCode, data);
        if (!selectedImageUri.equals("")) {
            Uri filePath = data.getData();
            try {
                Bitmap bitmap = BitmapFactory.decodeFile(selectedImageUri);
                ivAvatar.setImageBitmap(Bitmap.createScaledBitmap(bitmap, 120, 120, false)); 
            } catch (Exception e) {
                e.printStackTrace();
            }

        } else {
            Toast.makeText(getApplicationContext(), "Try Again!", Toast.LENGTH_LONG).show();
        }
}

谢谢！

Answer 1

它显然写在您的logcat Permission denied中，您需要在清单中提供READ权限。

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

Answer 2

您需要在清单文件中提供读取权限。

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