将Finish（）添加到ImageButton，单击自定义视图(add finish() to ImageButton click in custom view)
我使用自定义视图在每个布局的底部插入一个公共布局，并以编程方式添加了setonclicklistener。 但我想将finish（）添加到intent中，以便在打开新页面时上一页完成。 这个怎么做？
Custom View
public class MenuView extends RelativeLayout {
private LayoutInflater inflater;
public MenuView(Context context, AttributeSet attrs) {
super(context, attrs);
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.homemenu, this, true);
((ImageButton)this.findViewById(R.id.home)).setOnClickListener(home);
((ImageButton)this.findViewById(R.id.search)).setOnClickListener(search);
((ImageButton)this.findViewById(R.id.locate)).setOnClickListener(locate);
((ImageButton)this.findViewById(R.id.log)).setOnClickListener(log);
((ImageButton)this.findViewById(R.id.event)).setOnClickListener(event);
((ImageButton)this.findViewById(R.id.activities)).setOnClickListener(activities);
((ImageButton)this.findViewById(R.id.profile)).setOnClickListener(profile);
}
private OnClickListener home = new OnClickListener() {
public void onClick(View v) {
//getContext().startActivity(new Intent(getContext(), MainActivity.class));
Intent i = new Intent(getContext(), MainActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener search = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Search.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener locate = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Locate.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener log = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Log.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener event = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), CreateEvent.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener activities = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Activities.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener profile = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Profile.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
}
I used a custom view to insert a common layout in the bottom of every layout and added setonclicklistener programmatically. But I want to add finish() to intent so that on opening new page the previous page gets finish. How to do this?
Custom View
public class MenuView extends RelativeLayout {
private LayoutInflater inflater;

((ImageButton)this.findViewById(R.id.home)).setOnClickListener(home);
((ImageButton)this.findViewById(R.id.search)).setOnClickListener(search);
((ImageButton)this.findViewById(R.id.locate)).setOnClickListener(locate);
((ImageButton)this.findViewById(R.id.log)).setOnClickListener(log);
((ImageButton)this.findViewById(R.id.event)).setOnClickListener(event);
((ImageButton)this.findViewById(R.id.activities)).setOnClickListener(activities);
((ImageButton)this.findViewById(R.id.profile)).setOnClickListener(profile);
}
private OnClickListener home = new OnClickListener() {
public void onClick(View v) {
//getContext().startActivity(new Intent(getContext(), MainActivity.class));
Intent i = new Intent(getContext(), MainActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener search = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Search.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener locate = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Locate.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener log = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Log.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener event = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), CreateEvent.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener activities = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Activities.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
private OnClickListener profile = new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(getContext(), Profile.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
getContext().startActivity(i);
}
};
}
最满意答案
在你的方式
getContext().startActivity(i)
使用相同的方法，但您需要将getContext()转换为Activity
((Activity)getContext()).finish();
如果你在Fragment中使用它，你需要检查它的Activity与否。
if( getContext() instanceof Activity )
((Activity)getContext()).finish();
in the way you are doing
getContext().startActivity(i)
same way use but you need to convert getContext() to Activity
((Activity)getContext()).finish();
If anywhere you are using this from Fragment you need to check whether its Activity or not.
if( getContext() instanceof Activity )
((Activity)getContext()).finish();
