Finish activity in dialog class
提问by L3n95
In my MainActivityI call
在我MainActivity我叫
myDialog dialog = new myDialog(MainActivity.this);
dialog.show();
myDialogis my own class where I customize the dialog.
In the dialog is a button. I want that the MainActivityand the dialog finishes/dissappears when the button is pressed, because I start another Activity then.
How can I say in the myDialogclass, in the onClickListener, that the MainActivityshould finish()?
myDialog是我自己的课程，我可以在其中自定义对话框。在对话框中有一个按钮。我希望MainActivity当按下按钮时，对话框结束/消失，因为然后我启动了另一个活动。我怎么能在myDialog课堂上说，在onClickListener，MainActivity应该finish()？
Shortened code of my dialog:
我的对话框的缩短代码：
public class myDialog extends Dialog implements OnClickListener {
void onClick() {
Intent menu = new Intent(getContext(), menu.class);
getContext().startActivity(menu);
}
}

You can finish your Activity as below...
您可以按如下方式完成您的活动...
Intent intent = new Intent(context, YourSecondActivity.class);
context.startActivity(intent);
((Activity) context).finish();
Update:
更新：
In your constructor of you custom dialog class, get the activity context as below...
在您自定义对话框类的构造函数中，获取如下活动上下文...
Context mContext;
public myDialog(Context context) {
super(context);
this.mContext = context;
}
then in your onClick()method finish the activity as below...
然后在您的onClick()方法中完成如下活动...
@Override
public void onClick(View v) {
Intent menu = new Intent(mContext, menu.class);
mContext.startActivity(menu);
((Activity) mContext).finish();
}

Firstly in your dialog class pass the context of the caller activities say MainActivit.class context
首先在你的对话类中传递调用者活动的上下文，比如 MainActivit.class上下文
Now first close the dialog
现在首先关闭对话框
//so as to avoid the window leaks as on destroying the activity it's context would also get vanished.
dialog.dismiss();
and then
进而
((Activity) context).finish();
