Question

您好我在我的onMenuItemClick中调用ActivityCompat.requestPermission来授予WRITE_EXTERNAL_STORAGE权限。但是，不执行ActivityCompat.requestPermissions。

我的目标是API 23

我在清单中定义了

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
        android:maxSdkVersion="18"/>

这是我在onMenuItemClick

中调用的代码

                case R.id.id_captura:
                     if (ContextCompat.checkSelfPermission(ChatActivity.this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
                        dispatchTakePictureIntent();
                    } else {
                        if (ActivityCompat.shouldShowRequestPermissionRationale(ChatActivity.this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)) {

                        } else {
                            ActivityCompat.requestPermissions(ChatActivity.this,
                                    new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, WRITE_EXTERNAL_STORAGE_CTE
                            );
                        }
                    }
                    break;

这是我的onRequestPermissionsResult

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case WRITE_EXTERNAL_STORAGE_CTE: {
             if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                 dispatchTakePictureIntent();
            } else {
                AlertDialog.Builder alertDialog = new AlertDialog.Builder(this).setTitle("Permissions").setMessage("Permissions not granted ").setPositiveButton("Accept", null);
                alertDialog.show();
            }
            return ;
        }
    }
}

我定义了

private final int WRITE_EXTERNAL_STORAGE_CTE = 1;

问题是android:maxSdkVersion="18"，因为我的目标是api 23，权限是在运行时请求的，但也必须在清单文件中声明。删除该行就完成了这项工作。

在onMenuItemClick内部调用时，ActivityCompat.requestPermission未显示对话框
