How to make buttons to appear and disappear on the Onclick event

Question

我有2个按钮邀请和共享，如果我单击邀请，则会出现包含4个imageviews的linearlayout bar1，对于共享按钮，在这4个imageview选项中也将显示相同的linearlayout bar2，如果我单击邀请和共享按钮，则布局栏均会出现，但是对我来说，当我单击“邀请”或共享时，一次只能显示一个对应的栏...

Answer 1

if I understand you correctly something like this will do the trick:

invite.setOnClickListener(new OnClickListener(){
    public void onClick(View v){
        linearlayoutbar1.setVisibility(View.VISIBLE);
        linearlayoutbar2.setVisibility(View.GONE);
    }
});

share.setOnClickListener(new OnClickListener(){
    public void onClick(View v){
        linearlayoutbar2.setVisibility(View.VISIBLE);
        linearlayoutbar1.setVisibility(View.GONE);
    }
});

Answer 2

Insert LinearyLayout upon your requirements

<merge>
<LinearLayout
    android:id="@+id/main"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    android:visibility="gone"  
    />
<LinearLayout
    android:id="@+id/sub"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    android:visibility="gone"  
    />  
</merge>

depending upon your invite and share button you can put these code invite.setOnClickListener() or share.setOnClickListener()

Insert Visibility of LinearLayout according to your Logic

LinearLayout mainLayout=(LinearLayout)this.findViewById(R.id.main);
LinearLayout subLayout=(LinearLayout)this.findViewById(R.id.sub);

invite.setOnClickListener(new OnClickListener()
{
   public void onClick(View v)
    {
    mainLayout.setVisibility(View.VISIBLE);        
    }
});

 share.setOnClickListener(new OnClickListener()
 {
   public void onClick(View v)
    {
    subLayout.setVisibility(View.VISIBLE);        
    }
 });
