在Android中使用Intent选择任何文件 [英] Pick any file using intent in android

问题描述

我正在使用以下方法来调用选择任何文件，但是它无法正常工作.

I'm using following method to call pick any file but it doesn't work properly.

private void fileIntent(int file)
    {
        if ((ActivityCompat.checkSelfPermission(ICShowFileCabinetDetails.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) && Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, file);
        } else {
            Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
            intent.setType("*/*");
            startActivityForResult(Intent.createChooser(intent, "Select File"), file);
        }

    }

以下权限在清单中设置

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

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
 if (requestCode == SELECT_FILE && data != null) {
            try {
                mProPic = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());

                Uri selectedImage = data.getData();

                String[] filePathColumn = {MediaStore.Images.Media.DATA};

                Cursor cursor = getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
                cursor.moveToFirst();
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String picturePath = cursor.getString(columnIndex);

//                String filename = selectedImage.getLastPathSegment();

                String[] filenames = picturePath.split("\\/");


                int count = filenames.length;
                String name = filenames[count - 1];


                imagepickerselected = 1;
                UploadIamgeinServer(1, name);

            } catch (IOException e) {
                e.printStackTrace();
            }
        }
}

每当我单击选择按钮单击中的文件时，选择打开文件.但是所有文件都显示为隐藏状态，但图像除外，单击不起作用.如果不使用方法，则单击按钮即可正常工作.如果有人发现代码错误，请通知我.

Choose file getting open whenever i click to choose file in button click. But all files are shown like hidden except images, Click doest work. Without method in it button click works fine. If anyone found errors in code please let me know.

谢谢
