使用相同xml布局文件的多个按钮

Question

i want to create multiple button from same xml resource for this i am creating am xml layout in which i define button in aa xml file

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <Button
            android:id="@+id/inputbox"
            style="@style/textstyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/inputbox"
            android:text="B" />

</LinearLayout>

and then in code i create multiple button using button which i define in xml the code is like this

View view = inputboxview.findViewById(R.id.inputbox);
        ((ViewGroup) view.getParent()).removeView(view);

        //Add input boxes in control view
        for(int i=0; i<guess_world.length(); i++)
        {
            Button inputbox = new Button(context);
            //Drawable image = context.getResources().getDrawable(R.drawable.inputbox); 
            //inputbox.setBackgroundDrawable(image);
            //inputbox.set
            inputbox = (Button) view;
            inputbar.addView(inputbox);
        }

Now the problem is that when i create a single it's just work fine but when i create more than 1 button it gives me exception that

java.lang.RuntimeException: 
 java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

So, please me in this.

Answer 1

The error is normal, as it says, each view can only be added once.

Move your button XML into a separate file, and inflate it and add it to your LinearLayout inside your for loop.

Answer 2

We can't guess what is your "inputbar" object so we don't know where are you adding the views.

What you can do is this, assuming that your container has the id=@+id/container and is a LinearLayout:

LinearLayout container = (LinearLayout) findViewById(R.id.container);

for(int i=0; i<guess_world.length(); i++)
        {
            Button inputbox = new Button(context); //or inflate from xml
            inputbox.setId(i);
            // TODO: set width and height using LayoutParameters
            container.addView(inputbox);
        }
