Question

我想在Android中制作自己的图库但是我找不到在没有选择的情况下拍摄所有照片的方法。我试过这个：

Intent galleryIntent = new Intent(Intent.ACTION_PICK,
    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);

但打开了一个我必须选择一张或多张照片的意图。 有没有办法可以在不选择它们的情况下将它们全部带来？

这是它的示例代码

public class GetImageActivity extends Activity {

    private static final int SELECT_PICTURE = 1;

    private String selectedImagePath;
    private ImageView img;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        img = (ImageView)findViewById(R.id.ImageView01);

        ((Button) findViewById(R.id.Button01))
                .setOnClickListener(new OnClickListener() {
                    public void onClick(View arg0) {
                        Intent intent = new Intent();
                        intent.setType("image/*");
                        intent.setAction(Intent.ACTION_GET_CONTENT);
                        startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
                    }
                });
    }

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_PICTURE) {
                Uri selectedImageUri = data.getData();
                selectedImagePath = getPath(selectedImageUri);
                System.out.println("Image Path : " + selectedImagePath);
                img.setImageURI(selectedImageUri);
            }
        }
    }

    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);
    }
}
