我创建了一个自定义对话框和布局的xml：

I have created a custom dialog and a layout xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Tap Me"
        android:onClick="dialogClicked" />
</LinearLayout>

在对话框类我实现的方法dialogClicked（视图v）：

In the dialog class I've implemented the method "dialogClicked(View v)":

public class TestDialog extends Dialog {

 public TestDialog(final Context context)
 {
  super(context);
 }

 @Override
 protected void onCreate(final Bundle savedInstanceState)
 {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.dialog);
 }

 public void dialogClicked(final View view)
 {
  System.out.println("clicked");
 }

}

当我点击我得到一个NoSuchMethodExceptiondialogClicked按钮。设置onclick处理程序中的布局XML工作正常的活动，但不是在对话框。有任何想法吗？我做错了什么？

When I tap the button I get a NoSuchMethodException 'dialogClicked'. Setting the onClick handler in layout xml works fine for activities, but not in dialogs. Any ideas? What I'm doing wrong?

推荐答案

定义在活动的方法（dialogClicked）。 并修改TestDialog像下面的code：

Define the method (dialogClicked) in Activity. And modify TestDialog like the following code:

public class TestDialog extends Dialog {
 Context mContext;
 public TestDialog(final Context context)
 {

  super(context);
  mContext=context;
 }

 @Override
 protected void onCreate(final Bundle savedInstanceState)
 {
  super.onCreate(savedInstanceState);
  LinearLayout ll=(LinearLayout) LayoutInflater.from(mContext).inflate(R.layout.dialog, null);
  setContentView(ll); 
 }
}

我觉得它的工作原理：）

I think it works :)
