Android实现网络图片查看器和网页源码查看器

网络图片查看器

清单文加入网络访问权限：

view plain
|<!-- 访问internet权限 --> 
<uses-permission android:name="android.permission.INTERNET"/> 
 

界面如下：

示例：

view plain
<span style="FONT-WEIGHT: normal">public class MainActivity extends Activity { 
    private EditText imagepath; 
    private ImageView imageView; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main); 
         
        imagepath = (EditText) this.findViewById(R.id.imagepath); 
        imageView = (ImageView) this.findViewById(R.id.imageView); 
         
        Button button = (Button) this.findViewById(R.id.button); 
        button.setOnClickListener(new View.OnClickListener() {           
            public void onClick(View v) { 
                String path = imagepath.getText().toString(); 
                try{ 
                    byte[] data = ImageService.getImage(path);//获取图片数据 
                    if(data!=null){ 
                        //构建位图对象 
                        Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length); 
                        imageView.setImageBitmap(bitmap);//显示图片 
                    }else{ 
                        Toast.makeText(getApplicationContext(), R.string.error, 1).show();
