将图像保存在图库中

Question

这是我的代码,我希望保存图像按钮只是将图像保存到图库.

package com.nk_apps.hip.hop.lyric.wallpapers;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

public class Wallpapers extends Activity implements OnClickListener {
}
    ImageView display;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.wallpapers);

        display = (ImageView) findViewById(R.id.IVDisplay);
        ImageView image1 = (ImageView) findViewById(R.id.IVimage1);
        ImageView image2 = (ImageView) findViewById(R.id.IVimage2);
        ImageView image3 = (ImageView) findViewById(R.id.IVimage3);
        ImageView image4 = (ImageView) findViewById(R.id.IVimage4);
        ImageView image5 = (ImageView) findViewById(R.id.IVimage5);
        ImageView image6 = (ImageView) findViewById(R.id.IVimage6);
        ImageView image7 = (ImageView) findViewById(R.id.IVimage7);
        ImageView image8 = (ImageView) findViewById(R.id.IVimage8);
        ImageView image9 = (ImageView) findViewById(R.id.IVimage9);
        Button saveImage = (Button) findViewById(R.id.bSaveImage);

        image1.setOnClickListener(this);
        image2.setOnClickListener(this);
        image3.setOnClickListener(this);
        image4.setOnClickListener(this);
        image5.setOnClickListener(this);
        image6.setOnClickListener(this);
        image7.setOnClickListener(this);
        image8.setOnClickListener(this);
        image9.setOnClickListener(this);
        saveImage.setOnClickListener(this);
    }

    public void onClick(View v) {
        // TODO Auto-generated method stub

        switch (v.getId()) {

        case R.id.IVimage1:
            display.setImageResource(R.drawable.aotl);
            break;
        case R.id.IVimage2:
            display.setImageResource(R.drawable.ball_so_hard);
            break;
        case R.id.IVimage3:
            display.setImageResource(R.drawable.eye);
            break;
        case R.id.IVimage4:
            display.setImageResource(R.drawable.faded);
            break;
        case R.id.IVimage5:
            display.setImageResource(R.drawable.hiii_power);
            break;
        case R.id.IVimage6:
            display.setImageResource(R.drawable.i_invented_swag);
            break;
        case R.id.IVimage7:
            display.setImageResource(R.drawable.lifes_a_bitch);
            break;
        case R.id.IVimage8:
            display.setImageResource(R.drawable.mack_truck);
            break;
        case R.id.IVimage9:
            display.setImageResource(R.drawable.opposite);
            break;
        case R.id.bSaveImage:

            break;
        }

    } }

我想知道在最后一种情况下要放什么.如果我不应该把它放在那里我可以被告知究竟是怎么回事？

保存图库中的任何图像可以通过以下方式完成:

MediaStore.Images.Media.insertImage(getContentResolver(), yourBitmap, yourTitle , yourDescription);
