How to restrict the WebView inside in android program

问题

i want to restrict webView's limit inside some pixels which is have declared at the time of webView initialization .

View insertPoint = findViewById(R.id.layout);

WebView web = new WebView(this) ;
web.setBackgroundColor(Color.GRAY);
int lHeight = 200 ;
int lWidth = 200 ;


( (ViewGroup) insertPoint ).addView(web, lWidth, lHeight) ;

web.loadUrl("http://www.google.com");

Edited :

Full Screen is taken by that WebView , it is not residing inside 200px*200px .

Edited :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity"
    android:id="@+id/layout" >



</LinearLayout>

回答1:

Your code should work if you also add the line:

web.setWebViewClient(new WebViewClient());

Otherwise your code will start the browser(which is full screen). If you click BACK for example you should see your gray box.

You can try this code for setting the height width :

            WebView w =new WebView(this);
            LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
            w.setLayoutParams(lp);
            w.getLayoutParams().width = 200;
            w.getLayoutParams().height = 200;
            ( (ViewGroup) insertPoint ).addView(w) ;

Yes your code is working check layout xml file weather you have declared your layout_width,layout_height match_parent or fill_parent if so then change it to wrap_content it will work .

put this layout instead of your layout if it works then there is nothing wrong in your code otherwise u have problem in ur xml.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/layout"   >


</LinearLayout>

Activity class

 public class MainActivity extends Activity {


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        loadView();

    }
    public void loadView(){
        View insertPoint = findViewById(R.id.layout);

        WebView web = new WebView(this) ;
        web.setWebViewClient(new WebViewClient());
        web.setBackgroundColor(Color.GRAY);
        int lHeight = 200 ;
        int lWidth = 200 ;


        ((ViewGroup) insertPoint) .addView(web, lWidth, lHeight) ;

        web.loadUrl("http://www.google.com");

    }
