处理外部类中的主要活动对话框按钮

Question

我试图创建一个自定义对话框，按钮点击可能通过实例它的主要活动进行处理，有点像AlertDialog.Builder如何通过其setPositiveButton分配听众（）和setNegativeButton（）方法。

这是我做了什么：

// THE MAIN ACTIVITY 

public class main_code extends AppCompatActivity { 

    private commonModule comMod; 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     comMod = new commonModule(this);  
    } 

    private void showDialog() { 
    DialogInterface.OnClickListener dialogHandler = 
     new DialogInterface.OnClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int which) { 
     // process "PROCEED" button 
     } 
    }; 

    commonModule.myDialog customDialog = comMod.new myDialog(); 
    customDialog.inputBox(this, "Submit Results", 
     "Your results will be submitted.", dialogHandler); 
    } 
} 


// THE COMMON MODULE CLASS 

public class commonModule { 

    public commonModule(Context context){ 
    this.context = context; 
    this.activity = (Activity) context; 
    } 

    public class myDialog {  

    public void showDialog(Activity activity, String title, String message, 
          DialogInterface.OnClickListener dialogHandler) { 

     final Dialog panel = new Dialog(activity); 
     panel.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     panel.setContentView(R.id.customLayout); 
     panel.setCancelable(false); 

     TextView panelTitle = (TextView) panel.findViewById(R.id.title); 
     panelTitle.setTypeface(fontRes(PlayRegular)); 
     panelTitle.setText(title); 

     TextView msgboxText = (TextView) panel.findViewById(R.id.content); 
     msgboxText.setTypeface(fontRes(PlayRegular)); 
     msgboxText.setText(message); 

     Button button1 = (Button) panel.findViewById(R.id.button1); 
     button1.setTypeface(fontRes(PlayRegular)); 
     button1.setText("ABORT"); 
     button1.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      panel.dismiss(); 
     } 
     }); 

     Button button2 = (Button) panel.findViewById(R.id.button2); 
     button2.setTypeface(fontRes(PlayRegular)); 
     button2.setText("PROCEED"); 

     button2.setOnClickListener(dialogHandler); 
     // error: View.OnClickListener cannot be applied to Dialog.OnClickListener 

     panel.show(); 
    } 
    } 
} 

我尝试使用View.OnClickListener（）为好，但没有成功。我希望对话框构建器是通用的和通用的，因此，对于每个对话框，点击侦听器应该是唯一的。

任何建议将非常感激。

TIA。

您DialogHandler中更改为View.OnClickListener，而不是DialogInterface.OnClickListener：

private void showDialog() { 
    View.OnClickListener dialogHandler = 
     new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
     // process "PROCEED" button 
     } 
    }; 

    commonModule.myDialog customDialog = comMod.new myDialog(); 
    customDialog.inputBox(this, "Submit Results", 
     "Your results will be submitted.", dialogHandler); 
    } 

和公共模块：

public void showDialog(Activity activity, String title, String message, 
          View.OnClickListener dialogHandler) { 
    ... 
    button2.setOnClickListener(dialogHandler); 
    panel.show(); 
}
