我是Android新手,我正在开发自定义警报对话框

我想点击编辑按钮打开另一个对话框,代码如下

 if (v.getId() == R.id.edt_order) {                                  
        System.out.println(" edit buton click");                    
        System.out.println("Click my Order");
            System.out.println(" edit clickkkkkkkkkkkkkk");
         LayoutInflater li = LayoutInflater.from(getApplicationContext());
         View promptsView = li.inflate(R.layout.prompts, null);

         AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                 getApplicationContext());

         // set prompts.xml to alertdialog builder  
         alertDialogBuilder.setView(promptsView);    

         final EditText userInput = (EditText) promptsView
         .findViewById(R.id.editTextDialogUserInput); 

         // set dialog message
         alertDialogBuilder
         .setCancelable(false)
         .setPositiveButton("OK",
                 new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog,int id) {
                 // get user input and set it to result 
                 // edit text
                 //    result.setText(userInput.getText());

                 System.out.println("Click ok");    
                // insertData(userInput.getText().toString().trim());
                 Toast.makeText(getApplicationContext(), "Category added", 5000).show();
                 // loadSpinnerData();
             }
         })
         .setNegativeButton("Cancel",
                 new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog,int id) {
                 dialog.cancel();
             }
         }); 

         // create alert dialog   
          alertDialog = alertDialogBuilder.create();

         // show it
         alertDialog.show();                 
    }

但我得到一个例外,我的日志猫输出如下

即使我的redcross按钮工作正常,我已经使用相同的代码多次显示AlertDialog与TextView,但我没有得到代码的问题.任何帮助都非常感谢.提前致谢.

现在我得到了我想要的任何东西,但编辑和保存两者都有重叠.我想隐藏编辑(蓝色按钮)并清楚地显示可见的保存按钮.

解决方法:

如果您阅读getApplicationContext()中的文档,您会发现只有在需要生命周期与当前上下文不同的Context时才应该使用它.这不适用于您的示例并将此对象用作className类型的对象.我想在这里您可以使用

  AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);

要么

  AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(ClassNAme.this);

两者都应该有效.
