我的查询是,我怎么能显示与圆形按钮和表行的消息,当我点击圆形按钮与问号。
My query is, How can I display the messages corresponding to the rounded buttons and the table row , when I click on the rounded button with question mark.
我知道,我必须使用监听器?按钮,但我应该做的听众完全,这样,当我点击,它显示这些警报(图像),当我再次点击,它就会消失。
I know, I have to use listener for the ? button , but what should I do in listener exactly, such that when I click, it shows those alerts(images) and when I click again, it disappears.
有关此UI,我已经使用相对布局,建议在这里 - 对齐组件在所需位置 - 和它的工作非常适合我。
For this UI, I have used Relative layout as was suggested here -- Aligning components at desired positions -- and it worked perfect for me.
所以,我需要完全改变我的基地布局的完成呢?
So, do I need to change my base layout altogether for accomplishing this?
推荐答案
您可以使用的FrameLayout
为基准,为您的UI布局,然后添加一个 ImageView的
覆盖。例如:
You can use a FrameLayout
as the base for your ui layout and then add an ImageView
overlay. For example:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/MainFrame"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- Put your normal layout stuff here -->
</FrameLayout>
然后在你的code您可以创建的ImageView
,并把它添加到大型机
,它会覆盖你的用户界面,像这样的:
Then in your code you can create the ImageView
and add it to the MainFrame
and it will overlay your UI, like this:
FrameLayout mainFrame = (FrameLayout)findViewById(R.id.MainFrame);
ImageView overlay = new ImageView(this);
overlay.setImageBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.overlay));
mainFrame.addView(overlay);
再后来,你可以调用:
Then later you can call:
mainFrame.removeView(overlay);
有它走了。
