本文为大家分享了Android使用线程获取网络图片的具体代码，供大家参考，具体内容如下

AndroidManifest.xml

<"1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.zdcrobot.handlermessage"> <uses-permission android:name="android.permission.INTERNET"></uses-permission> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity" android:label="@string/app_name" android:theme="@style/AppTheme.NoActionBar"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>

activity_main.xml

<"1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" tools:context="com.zdcrobot.handlermessage.MainActivity"> <LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="加载图片"/> <ImageView android:id="@+id/image1" android:layout_width="match_parent" android:layout_height="500dp" /> </LinearLayout> </android.support.design.widget.CoordinatorLayout>

MainActivity.class

package com.zdcrobot.handlermessage; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.os.Bundle; import android.os.Handler; import android.os.Message; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.Button; import android.widget.ImageView; import java.io.IOException; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.URL; public class MainActivity extends AppCompatActivity { private Button button; private ImageView imageView; private String imagPath = "http://pica.nipic.com/2007-11-09/200711912453162_2.jpg"; private final int IS_FINISH = 1; private Handler handler = new Handler(){ @Override public void handleMessage(Message msg) { Bitmap bitmap = (Bitmap)msg.obj; imageView.setImageBitmap(bitmap); } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); button = (Button)findViewById(R.id.button1); imageView = (ImageView)findViewById(R.id.image1); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { new Thread(new MyClass()).start(); } }); } public class MyClass implements Runnable{ @Override public void run() { Bitmap bitmap = null; try { URL url = new URL(imagPath); HttpURLConnection httpURLConnection = (HttpURLConnection)url.openConnection(); httpURLConnection.setDoInput(true); httpURLConnection.connect(); InputStream inputStream = httpURLConnection.getInputStream(); bitmap = BitmapFactory.decodeStream(inputStream); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } Message message = Message.obtain(); message.obj = bitmap; message.what = IS_FINISH; handler.sendMessage(message); } } }
