Question

我做了一个非常简单的壁纸应用程序，之前使用过相同的代码。我没有错误，但由于某种原因我的图像不可点击，我错过了一些可能有人帮助...这是迄今为止的代码

import java.io.IOException;
import java.io.InputStream;

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


public class Nflwallpapers extends Activity implements View.OnClickListener{

ImageView display;
int toPhone;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    toPhone = R.drawable.azcard1;

    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);
    Button setWall = (Button)findViewById(R.id.setwallpaper);
    image1.setOnClickListener(this);
    image2.setOnClickListener(this);
    image3.setOnClickListener(this);
    image4.setOnClickListener(this);
    image5.setOnClickListener(this);
    image6.setOnClickListener(this);
    setWall.setOnClickListener(this);
}

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

    switch (v.getId()){
    case R.id.IVimage1:
        display.setImageResource(R.drawable.azcard1);
        toPhone =R.drawable.azcard1;
        break;
    case R.id.IVimage2:
        display.setImageResource(R.drawable.azcard2);
        toPhone =R.drawable.azcard2;
        break;
    case R.id.IVimage3:
        display.setImageResource(R.drawable.azcard3);
        toPhone =R.drawable.azcard3;
        break;
    case R.id.IVimage4:
        display.setImageResource(R.drawable.azcard4);
        toPhone =R.drawable.azcard4;
        break;
    case R.id.IVimage5:
        display.setImageResource(R.drawable.azcard5);
        toPhone =R.drawable.azcard5;
        break;
    case R.id.IVimage6:
        display.setImageResource(R.drawable.azcard6);
        toPhone =R.drawable.azcard6;
        break;
    case R.id.setwallpaper:
        InputStream yes = getResources().openRawResource(toPhone);
        Bitmap whatever = BitmapFactory.decodeStream(yes);
        try{
            getApplicationContext().setWallpaper(whatever);
        }catch(IOException e){
            e.printStackTrace();
        }
        break;

    }

}
