如何从我的Android设备获取所有图像和照片而不是从SD卡？

Question

我想从我的Android设备获取所有图像/照片/壁纸与图像保存路径.

我已经实现了从sdcard收集图像的代码,如下所示:

String[] mProjection = {
    MediaStore.Images.Media._ID,
    MediaStore.Images.Media.DATA
};

mCursor = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
    mProjection,
    null,
    null,
    MediaStore.Images.Media.DEFAULT_SORT_ORDER);

从上面的代码我只能从sdcard中检索图像.但如果图像在设备手机内存中可用,那么我该如何检索图像/照片/壁纸？如果我使用INTERNAL_CONTENT_URI它不会返回wallapers info其他图像信息

请任何身体帮助我....

试试这个答案，这会起作用：

public static final int GALLERY_CODE = 322;

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(
    intent,
    "Select Picture"),
    GALLERY_CODE);


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//Assinging on corresponding import
super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == GALLERY_CODE && resultCode == RESULT_OK) {
        Uri selectedImageUri = data.getData();
        selectedImagePath = getPath(selectedImageUri);

        try {

            //add logic for coping file

        } catch (Exception e) {
        }
    }
}

public String getPath(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = managedQuery(uri, projection, null, null, null);

    int column_index = cursor
        .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);

    cursor.moveToFirst();
    return cursor.getString(column_index);
}
