我需要将我的 ImageView 转换为 TextView，这样我就可以在单击时将 ListView 中的图像切换为文本。如何将 ImageView 转换为 TextView？
我需要图像的列表视图 (R.DRAWABLE.ka_se_kamal) WHEN
单击应更改为 (R.STRING.miwok_letter_a)
其他问题没有解决我的问题的原因是所有解决方案都提供通过 setBackgroundResource 更改图像视图，单击时可以在列表视图中更改图像。但为此我需要为列表中的所有项目创建图像，这可能会占用大量资源。.如果列表视图中的图像可以更改为文本视图，那就更好了..
您必须同时使用 imageView 和 textView。您可以更改可见性。当用户单击 imageView 时，您可以将其可见性设置为 gone 并将 textView 的可见性设置为可见。这是对我有用的代码：
Boolean flag =false;
@Override
public void onClick(View view) {
// Toast.makeText(getContext(), "ImageView clicked for the row = "+view.getTag().toString(), Toast.LENGTH_SHORT).show();
if(flag){
imageView.setAlpha(255);
// imageView.setImageResource(R.drawable.a_se_anaar);
onClickTextView.setVisibility(View.INVISIBLE);
flag = false;
}else{
imageView.setAlpha(0);
onClickTextView.setVisibility(View.VISIBLE);
flag =true;
