Question

I’m trying to put a button at the bottom of a webview. For some reason, it keeps showing up at the top. Here’s my code:

    webview = new WebView(this);
    RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);
    Button myButton = new Button(this);
    myButton.setId(11);
    LayoutParams buttonParams = new LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

    //          params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    myButton.setText("A Button!");
    myButton.setLayoutParams(new LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));

    buttonParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, -1);
    myButton.setLayoutParams(buttonParams);

    webview.setLayoutParams(params2);
    //setBackgroundcolor(0) - You must make the background color transparent before setting backgroundResource
    webview.setBackgroundColor(0);
    webview.setBackgroundResource(R.drawable.background);
    webview.addView(myButton);

Edit —

I’m gonna go ahead and set up the base of my reusable view in xml. I’ll just use ScrollView with a RelativeLayout inside of it (containing my WebView and Button). The reason is because I only want the Button to show up once I reach the end of the webpage.

WebView extends AbsoluteLayout, so you can’t use RelativeLayout.LayoutParams. Moreover, AbsoluteLayout is deprecated, and WebView is definitely not a view to be used as a container.

You can overlay a RelativeLayout over the WebView putting them in a FrameLayout, they’ll get piled up, with the last view added (your RelativeLayout) at the top.
