Android 打开文件管理器，并返回选中文件的path

1:

点击触发事件：

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);intent.setType("*/*");intent.addCategory(Intent.CATEGORY_OPENABLE);try {    startActivityForResult( Intent.createChooser(intent, "Select a File to Upload"), REQUEST_CODE_GET_IMAGE);} catch (android.content.ActivityNotFoundException ex) {    Toast.makeText(ResourceActivity.this, "Please install a File Manager.",  Toast.LENGTH_SHORT).show();}

2:

处理返回结果

@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {    super.onActivityResult(requestCode, resultCode, data);    if(resultCode != RESULT_OK){        return;    }    switch (requestCode){        case REQUEST_CODE_GET_IMAGE :            if (resultCode == RESULT_OK) {                    Uri selectedMediaUri = data.getData();                    String path = FileUtils.getPath(ResourceActivity.this, selectedMediaUri);            }            break;        default:            break;    }}

/** * 获取文件选择器选中的文件路径 * @param context * @param uri * @return */public static String getPath(Context context, Uri uri) {    if ("content".equalsIgnoreCase(uri.getScheme())) {        String[] projection = { "_data" };        Cursor cursor = null;        try {            cursor = context.getContentResolver().query(uri, projection,null, null, null);            int column_index = cursor.getColumnIndexOrThrow("_data");            if (cursor.moveToFirst()) {                return cursor.getString(column_index);            }        } catch (Exception e) {            // Eat it        }    }    else if ("file".equalsIgnoreCase(uri.getScheme())) {        return uri.getPath();    }    return null;}
