在onClick上切换布局的可见性 [英] Toggle visibility of a layout on onClick
本文介绍了在onClick上切换布局的可见性的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
当我单击按钮时,我需要将此布局设置为可见,我的java就像这样:
I need to set this layout visible when i click a button, my java is like:
Layout propLayout = (Layout) findViewById(R.id.properLayout);
public void propsBtn(View view) {
propLayout.setVisiblity(View.Visible);
}
我知道我对版式行完全错了!如果有人可以告诉我如何设置正确的位置,我将不胜感激:)
I know I'm totally wrong with the layout line! I'll be very grateful if someone could show me how to set it right :)
这是我的XML:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/mainBackGround"
tools:context="com.myapplication2.app.MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="8dp">
...contents...
</RelativeLayout>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone"
android:id="@+id/properLayout">
<RelativeLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_gravity="bottom"
android:padding="8dp">
...contents...
</RelativeLayout>
</LinearLayout>
推荐答案
DerGolem给出了正确答案,但他随后将其删除,所以我现在在这里报告:
DerGolem gave the right answer but he then deleted it, so I report it here now:
//First we set visibility value of interested layout either to gone, visible or invisible
android:visibility="gone"
然后在onCreate下这样写:
Then under onCreate write like:
//specify the button that has to handle visibility
ImageButton properties = (ImageButton) findViewById(R.id.propBtn);
//And the layout we want to change is visibility
final LinearLayout propLayout = (LinearLayout) findViewById(R.id.properLayout);
properties.setOnClickListener
(
new View.OnClickListener()
{
public void onClick(View v)
{
if (propLayout.getVisibility() == View.VISIBLE)
{
propLayout.setVisibility(View.INVISIBLE);
}
else
{
propLayout.setVisibility(View.VISIBLE);
}
}
}
);
