我需要在代码中创建以下 xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:gravity="right"
android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#00000000"
>
<android.webkit.WebView android:layout_width="fill_parent"
android:id="@+id/adview"
android:scrollbars="none"
android:layout_height="50dp"
android:layout_alignParentLeft="true"
android:layout_alignParentBottom="true"
></android.webkit.WebView>
<Button android:layout_width="wrap_content" android:text="x" android:textColor="#000000"
android:layout_height="wrap_content" android:id="@+id/hide_popup_button" android:background="#00000000"
android:layout_alignTop="@+id/adview" android:layout_alignParentRight="true"></Button>
</RelativeLayout>
I use the code below but I get a Force close:
我使用下面的代码，但我得到一个Force close：
RelativeLayout popwindow=new RelativeLayout(this);
RelativeLayout.LayoutParams rl= new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 50);
popwindow.setLayoutParams(rl);
WebView w= new WebView(this);
w.setId(0X100);
w.setScrollContainer(false);
android.widget.RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)w.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
Button b=new Button(this);
b.setId(0X101);
b.setText("X");
b.setBackgroundColor(Color.TRANSPARENT);
b.setLayoutParams(new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
android.widget.RelativeLayout.LayoutParams paramsbut = (RelativeLayout.LayoutParams)b.getLayoutParams();
paramsbut.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
paramsbut.addRule(RelativeLayout.ALIGN_TOP,w.getId() );
popwindow.addView(w,params);
popwindow.addView(b,paramsbut);
setContentView(popwindow);
I need suggestions on how to make that xml layout through java code.

You should post any exception you get in your question. See if this helps:
您应该发布您在问题中遇到的任何异常。看看这是否有帮助：
RelativeLayout popwindow=new RelativeLayout(this);
FrameLayout.LayoutParams rl= new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, 50);
popwindow.setLayoutParams(rl);
WebView w= new WebView(this);
w.setId(0X100);
w.setScrollContainer(false);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, 50);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
w.setLayoutParams(params);
Button b=new Button(this);
b.setId(0X101);
b.setText("X");
b.setBackgroundColor(Color.TRANSPARENT);
RelativeLayout.LayoutParams bparams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, ReloativeLayout.LayoutParams.WRAP_CONTENT);
bparams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
bparams.addRule(RelativeLayout.ALIGN_TOP, w.getId());
b.setLayoutParams(bparams);
popwindow.addView(w);
popwindow.addView(b);
setContentView(popwindow);
Custom component holding the WebViewand the Button:
包含WebView和 的自定义组件Button：
public class CustomRelativeLayout extends RelativeLayout {
private WebView mWebView;
private Button mButton;
public CustomRelativeLayout(Context context) {
super(context);
mWebView = new WebView(context);
mWebView.setId(0X100);
mWebView.setScrollContainer(false);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT, 50);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
mWebView.setLayoutParams(params);
mButton = new Button(context);
mButton.setId(0X101);
mButton.setText("X");
mButton.setBackgroundColor(Color.TRANSPARENT);
RelativeLayout.LayoutParams bparams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
bparams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
bparams.addRule(RelativeLayout.ALIGN_TOP, mWebView.getId());
mButton.setLayoutParams(bparams);
addView(mWebView);
addView(mButton);
}
public WebView getTheWebView() {
return mWebView;
}
public Button getTheButton() {
return mButton;
}
}
To use that component:
要使用该组件：
CustomRelativeLayout popWindow = new CustomRelativeLayout(this);
FrameLayout.LayoutParams rl= new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, 50);
setContentView(popWindow);
// get a reference to the WebView and the Button
WebView w = popWindow.getTheWebView();
Button b = popWindow.getTheButton();
