Question

我需要在图片点击时导航到下一页。使用充气器获取视图并将其分配给行。通过使用行我正在访问元素＆＃34;学习＆＃34;这是＆＃34; dialog_layout＆＃34;中的ImageView。视图。现在我需要为那个＆＃34; Imgview＆＃34;设置onclicklister。我已经编写了代码但是当我点击imageview时它没有导航。我在代码中犯了任何错误..

 public void onItemClick(AdapterView<?> parent, View view, int position,
            long id) {
        // TODO Auto-generated method stub
        try{
            final Dialog dialog = new Dialog(ListViewGallery.this);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setContentView(R.layout.dialog_layout);
            Window window = dialog.getWindow();
            window.setLayout(Parent.getHeight()/2, Parent.getHeight()/2);
            dialog.show();
            ImageView ImgView=(ImageView)findViewById(R.id.learn);
            ImgView.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {       
                    Intent intent=new Intent(ListViewGallery.this,LearnLayoutAnimals.class);
                    startActivity(intent);          
                }
            });

        }catch(Exception e){
            Log.v("dd",e.toString());
        }


    }

由于在显示对话框后给视图充气，您看到的ImageView和已膨胀的ImageView是不同的对象。改变它

final Dialog dialog = new Dialog(ListViewGallery.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

View row=LayoutInflater.from(ListViewGallery.this).inflate(R.layout.dialog_layout, parent,false);
ImageView ImgView=(ImageView)row.findViewById(R.id.learn);
ImgView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
      Intent intent=new Intent(ListViewGallery.this,LearnLayoutAnimals.class);
      startActivity(intent);
}
});
dialog.setContentView(row);
dialog.show();

Imageclick onclicklistener不使用LayoutInflater的实现
