Answer 1

试试这个java代码......我希望它对你有用

LinearLayout layout=new LinearLayout(this);

LayoutParams layoutParam=new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);  
        layout.setLayoutParams(new ScrollView.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));

layout.setOrientation(LinearLayout.VERTICAL);
WebView detailsView=(WebView)findViewById(R.layout.jr_lb_view_preview_switcher);
layout.addView(detailsView, layoutParam);
detailsView.setVerticalScrollBarEnabled(true);
ScrollView scroll=new ScrollView(this);
scroll.addView(layout);
setContentView(scroll);

制作像这样的缩放类

import android.content.Context;

import android.graphics.Canvas;

import android.graphics.drawable.Drawable;

import android.view.KeyEvent;

import android.view.View;
import android.widget.Button;
import android.widget.ImageButton;


public class Zoom extends View {


    private Drawable image;
    ImageButton img,img1;

    private int zoomControler=20;


    public Zoom(Context context)

    {

            super(context);

            image=context.getResources().getDrawable(R.drawable.j);
            //image=context.getResources().getDrawable(R.drawable.icon);

            setFocusable(true);



    }

    @Override

    protected void onDraw(Canvas canvas) {

            // TODO Auto-generated method stub

            super.onDraw(canvas);

    //here u can control the width and height of the images........ this line is very important

    image.setBounds((getWidth()/2)-zoomControler, (getHeight()/2)-zoomControler, (getWidth()/2)+zoomControler, (getHeight()/2)+zoomControler);

            image.draw(canvas);

    }


    @Override

    public boolean onKeyDown(int keyCode, KeyEvent event) {



            if(keyCode==KeyEvent.KEYCODE_DPAD_UP)// zoom in

                    zoomControler+=10;

            if(keyCode==KeyEvent.KEYCODE_DPAD_DOWN) // zoom out

                    zoomControler-=10;

            if(zoomControler<10)

                    zoomControler=10;



            invalidate();

            return true;

    }

并像

一样使用它

 setContentView(new Zoom(this));
