Question

我有一些警告对话框，我的问题是当我点击右上角的十字（X）时没有setNegative按钮时如何关闭警告对话框。

imgmain.setImageResource(imgID);
        imgmain.setOnClickListener(new OnClickListener() {          
            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                /*Intent MyIntentDetailItem=new Intent(getBaseContext(), ViewDetailItemFullscreen.class);
                Other_class.setItemCode(timgName);
                startActivity(MyIntentDetailItem);*/

                LayoutInflater li = LayoutInflater.from(ViewDetailItem.this);
                final View inputdialogcustom = li.inflate(R.layout.activity_view_detail_item_fullscreen2, null);                
                final AlertDialog.Builder alert = new AlertDialog.Builder(ViewDetailItem.this); 

                ImageView btnclose = (ImageView) inputdialogcustom.findViewById(R.id.btnclosepopup);
                btnclose.setOnClickListener(new View.OnClickListener() {
                    public void onClick(View v) {

//DOING SOMETHING
                    }
                });

       }
}

Answer 1

假设您有X图片，那么您可以按照以下方式执行此操作，

private static AlertDialog.Builder alert; // at class level

其余代码相同

alert = new AlertDialog.Builder(ViewDetailItem.this); 
btnclose.setOnClickListener ( new OnClickListener () 
{
     @Override 
     public void onClick ( View view )
     {
          alert.dismiss(); // Add this line in your code.
     }
});

Answer 2
