Android - Close activity on button click
提问by Tamas Koos
I have a Bus timetable app with a lot of activity (around 120). It is working smoothly, but after opening several activities, it gets slower. So I have buttons that opens an other activity. I want to kill the former activity after the other is opened. How can I make it? Thanks in advance.
我有一个包含大量活动（大约 120 次）的巴士时刻表应用程序。运行很顺利，但是打开几个活动后，速度变慢了。所以我有打开其他活动的按钮。我想在另一个活动打开后杀死前一个活动。我怎样才能做到？提前致谢。
My button click action:
我的按钮点击动作：
addListenerOnButton();
}
public void addListenerOnButton() {
final Context context = this;
button101 = (Button) findViewById(R.id.button101);
button101.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, B10oda.class);
startActivity(intent);
}
});

Call finish()
称呼 finish()
Intent intent = new Intent(context, B10oda.class);
startActivity(intent);
finish();
But think again if you really want to finish the Activity. You could do some profiling and find out why your app is running slow.
但是，如果您真的想完成活动，请再想一想。您可以进行一些分析并找出您的应用程序运行缓慢的原因。
Also 120 Activities seems too much. See if you could change your design and reduce the number of Activities.
还有 120 个活动似乎太多了。看看你是否可以改变你的设计并减少活动的数量。
