提问by user3683036
i want to have two relativelayout in first relativelayout have map and in second relativelayout i have the list..,i want on starting only layout with map will be visible on screen with a button,,when i click on button then layout with listview get open from right side with new new button on the top of it,,and prevoius button get hide.and screen get divided with two parts with different layouts..i have done some thing but from starting onward m getting half half screen.
我想在第一个相对布局中有两个相对布局有地图，在第二个相对布局中我有列表..，我想在开始时只有地图布局将通过按钮在屏幕上可见，当我单击按钮时，使用列表视图进行布局得到从右侧打开，顶部有新按钮，前一个按钮隐藏。屏幕被分成具有不同布局的两个部分。
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Try this:
尝试这个：
You are getting layout1 in half screen from starting due to weight property. You can try not giving weight in starting and give it programatically on button click.
由于重量属性，您从一开始就在半屏中获得 layout1。您可以尝试在开始时不给予权重，并在单击按钮时以编程方式给予权重。
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
button1.setVisibility(View.GONE); //hide old button
layout2.setVisibility(View.VISIBLE); //show layout2
//set Relativelayout 1 to half screen
RelativaLayout.LayoutParams params = layout1.getLayoutParams();
params.weight = 0.5;
layout1.setLayoutParams(params);
}
});
Hope this helps.
希望这可以帮助。

You can try with isShown()as suggested by Amiya
您可以isShown()按照 Amiya 的建议尝试
<b>
button2.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view) {
if(button1.isShown()) {
// Your_Staff
}
else{
// Your_Staff
}
}
});

From my view you did not set the orientation in the LinearLayoutto be vertical for the two RelativeLayouts. I also suggests you put the map and Buttonin a FrameLayoutas well instead of RelativeLayout.
在我看来，您没有LinearLayout将两个 RelativeLayouts的方向设置为垂直。我还建议您将地图和Button放在 a 中FrameLayout，而不是RelativeLayout.

Set visibility as Goneinstead of Invisible
将可见性设置为Gone而不是Invisible
