为什么我不能设置onClickListener在对话框视图按钮? [英] Why I can not set onClickListener for a button in a dialog view?
问题描述
我有如下所述的自定义对话框。
I have a custom dialog which described below.
我的自定义对话框布局( * my_dialog.xml * )只包含了解雇按钮:
My Custom Dialog layout (*my_dialog.xml*) which only contain a "dismiss" button:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
>
<Button
android:id="@+id/dismiss_btn"
android:layout_width="100dip"
android:layout_height="30dip"
android:layout_centerHorizontal="true"
android:text="Dismiss me"
android:textSize="8dip"
android:textColor="#ffffff"
/>
</RelativeLayout>
我的对话视图类:
my dialog view class:
public class MyDialog extends Dialog{
public MyDialog(Context context){
super(context);
}
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.my_dialog);
Button dismissMeBtn = (Button)findViewById(R.id.dismiss_btn);
/** ERROR Message when set onClickListener below (throw by eclipse editor)**/
// The method setOnClickListener(View.OnClickListener) in the
// type View is not applicable for the arguments (new DialogInterface.OnClickListener(){})
dismissMeBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
MyDialog.this.dismiss();
}
});
getWindow().setLayout(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
}
}
由于code所示上面,我有一个 * dismiss_btn * 对话框中的按钮,我想关闭该对话框时,解雇按钮是pressed,但我在code得到一个错误时的的 setOnClickListener 的作为解雇按钮(如code所示)。
As the code indicated above, I have a "*dismiss_btn*" button on the dialog, I would like to dismiss the dialog when the dismiss button is pressed, but I got an error in my code when setOnClickListener for the dismiss button (as indicated in the code).
错误信息(由Eclipse编辑器错误掷):
Error message (error throw by eclipse editor):
在类型视图的方法setOnClickListener(View.OnClickListener)不适用于参数(新DialogInterface.OnClickListener(){})
为什么我得到了错误?为什么我不能设置onClickListener一个按钮,在对话框的看法?
Why I got the error? Why I can not set onClickListener for a button in a dialog view?
推荐答案
由于日食认为这是DialogInterface onClickListener,但你需要查看onClickListener所以这将是
As eclipse thinks it is DialogInterface onClickListener but you need a View onClickListener so it will be
dismissMeBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
MyDialog.this.dismiss();
}
});
