Question

我从db填充了gridview。当我打开一些图像时，它们会卡在布局的顶部。可能导致什么？

我注意到一些图像直接在布局中间打开，这是我真正想要的。而一些图像只是＆＃34;下降＆＃34;双击后缩小它们，在正确的位置。

Gridview活动

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_grid_view);

    TextView id = (TextView) findViewById(R.id.i_id);

    Intent i = getIntent();
    i_id = i.getStringExtra(TAG_ID);

    id.setText(i_id);

    mGridView = (GridView) findViewById(R.id.gridView);
    mProgressBar = (ProgressBar) findViewById(R.id.progressBar);

    //Initialize with empty data
    mGridData = new ArrayList<>();
    mGridAdapter = new GridViewAdapter(this, R.layout.grid_item_layout, mGridData);
    mGridView.setAdapter(mGridAdapter);

    //Grid view click event
    mGridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            //Get item at position
            GridItem item = (GridItem) parent.getItemAtPosition(position);

            Intent intent = new Intent(GridViewActivity.this, DetailsActivity.class);
            intent.putExtra("image", item.getImage());
            startActivity(intent);
        }
    });

    //Start download
    new AsyncHttpTask().execute(FEED_URL);
    mProgressBar.setVisibility(View.VISIBLE);
}

详情活动

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_details);

    Intent i = getIntent();
    String image = i.getStringExtra("image");

    //Set image url
    imageView = (ImageView) findViewById(R.id.grid_item_image);
    Picasso.with(DetailsActivity.this).load(image).into(imageView);
    mAttacher = new PhotoViewAttacher(imageView);

    Uri bmpUri = getLocalBitmapUri(imageView);

    shareIntent = new Intent();
    shareIntent.setAction(Intent.ACTION_SEND);
    shareIntent.setType("image/*");
    shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);

我自己发现了这个错误。我不知道为什么但PhotoviewAttacher造成了这个问题。刚删除它并使用此课程https://github.com/MikeOrtiz/TouchImageView
