Android 带有imageview和文本的自定义imageadapter

如何使用图像本身和文本将图像添加到gridview中。我试图制作自定义图像适配器，但由于某种原因无法工作，在imgView.setLayoutParams（新的GridView.LayoutParams（85，85））上出现崩溃

新问题如何从映像适配器中添加和删除。。。我需要的行为就像一个图片与a，我添加了相同的图片与文字ab，所以应该有2张图片，然后我可以删除一个与a

“imgView”是ConvertView的子级，它是从R.layout.album_图像中膨胀出来的，该图像只是一个线性布局。因此，在设置布局参数时，它需要是父视图组类型。所以LinearLayout.LayoutParams工作正常

假设您想设置“ConvertView”的大小，那么在这种情况下，它需要是GridView.LayoutParams，因为“ConvertView”被添加到父项GridView中

希望你得到它

我认为imageview的父级是线性布局。您试过了吗？如何从imageadapter中添加和删除。我在imageadapter中有一张图片，我希望每次都在textview中添加相同的图片，并使用不同的名称删除该图片和更新imageadapter。很简单，您需要更改适配器中的数据（例如mThumbIds），然后使适配器无效请参见
