Android：将自己的视图添加到LinearLayour

Question

I have created an own View:

    private class SampleView extends View {

and I want to "plant" this View into a LinearLayout which I created in an xml file. How do I do that? Can someone help me?

Answer 1

add in your layout file

<LinearLayout >

<com.yourpackagename.SampleView />

<LinearLayout> 

or

LinearLayout lLayout = (LinearLayout)findViewById(R.id.linearlayout);
lLayout.addView(new SampleView());

Answer 2

Just use the fully qualified name of your custom view class

<LinearLayout ...>
  <your.package.SampleView 
    android:layout_width=".."
    android:layout_height=".."
    ..
  >
  </your.package.SampleView >
  ..
</LinearLayout>

However, remove "private" from your class definition, and if it a nested class add static .

You can't use inner classes at this point

Answer 3

Try to add your custom View like this:

<view
   class="test.project.app.Compass$SampleView"
   //... other attributes
/>

Your custom View class must be public and static for the above code to work. Another option is to put the SampleView in its own file and simply use the code from the answers above.
