Android 怎么查看网络的方法
随着智能手机的普及,尤其是基于安卓系统的广泛使用,使android开发具有很好的前景.下面分享一个Android 怎么查看网络的方法. 第一步:下面是具体布局文件 android:id="@+id/picturepagh" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello_world" / android:id="@+id/btn" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="查看" / android:id="@+id/imageView" android:layout_width="fill_parent" android:layout_height="px" / 第二步:在MainActivity中进行图示代码编写 public class MainActivity extends Activity { private Button btn; private EditText path; private ImageView imgview; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btn = (Button) findViewById(R.id.btn); path = (EditText) findViewById(R.id.picturepagh); imgview = (ImageView) findViewById(R.id.imageView); btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Log.i("CLICK", ((Button) v).getText().toString()); new Thread(runa).start(); } }); } public void setView() { String picturepath = path.getText().toString(); byte[] data = null; try { data = ImageService.getImage(picturepath); Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);// BitmapFactory：工厂！ Looper.prepare();// 必须调用此方法，看源看器2022年最新直播源码要不然会报错 Message msg = new Message(); msg.what = 0; msg.obj = bitmap; handler.sendMessage(msg); } catch (Exception e) { Toast.makeText(getApplicationContext(),码安八卦运算起步副图源码 "获取错误", 1).show(); } } private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { if (msg.what == 0) { updateImageView((Bitmap) msg.obj); } } }; private Runnable runa = new Runnable() { @Override public void run() { setView(); } }; private void updateImageView(Bitmap bm) { imgview.setImageBitmap(bm); } } 第三步,添加一个流处理工作类StreamTool public class StreamTool { public static byte[] read(InputStream ins) throws Exception { ByteArrayOutputStream outstream = new ByteArrayOutputStream(); byte[] buffer = new byte[]; int length = 0; while ((length = ins.read(buffer)) -1) { outstream.write(buffer, 0, length); } outstream.close(); return outstream.toByteArray(); } } 第四步、添加一个ImageService服务类，卓开唯品会上化妆品正品溯源码里面包含一个获取网络数据的源图短视频电商平台源码怎么做方法； public class ImageService { // 获取网络的数据 public static byte[] getImage(String picturepath) throws Exception { URL url = new URL(picturepath); HttpURLConnection conn = (HttpURLConnection) url.openConnection();// 基于http协议的连接对象 conn.setConnectTimeout();// 秒； conn.setRequestMethod("GET");// 大写 if (conn.getResponseCode() == ) { InputStream ins = conn.getInputStream(); return StreamTool.read(ins); } return null; } } Instagram APP
