Android Studio 扫描二维码并解析跳转

很久没有做小项目了，今天有空就顺便做了个简单的扫描二维码并解析跳转。

     

   1.在app里面的libs文件中集成lib-zxing包

   2.在app文件中的build添加红色框类包名

   3.在activity_main.xml中添加按钮

<Button
    android:id="@+id/btn"
    android:layout_width="150dp"
    android:layout_height="100dp"
    android:text="扫描二维码跳转" />

   4.在MainActivity.java中添加运行解析代码

package com.example.zx;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import com.uuzuche.lib_zxing.activity.CaptureActivity;
import com.uuzuche.lib_zxing.activity.CodeUtils;

public class MainActivity extends AppCompatActivity {
    /**
     * 扫描跳转Activity RequestCode
     */
    public static final int REQUEST_CODE = 111;
    /**
     * 扫描跳转按钮
     */
    private Button btn=null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn=(Button)findViewById(R.id.btn);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, CaptureActivity.class);
startActivityForResult(intent,REQUEST_CODE);}});}
    @Override 
    protected void onActivityResult(
            int requestCode, int resultCode, Intent data) {
        /**
         * 处理二维码扫描结果
         */
        if (requestCode == REQUEST_CODE) {
            //处理扫描结果（在界面上显示）
            if (null != data) {
                Bundle bundle = data.getExtras();
                if (bundle == null) {
                    return;}
                if (bundle.getInt(CodeUtils.RESULT_TYPE)
                        == CodeUtils.RESULT_SUCCESS) {
                    String result = 
                            bundle.getString(CodeUtils.RESULT_STRING);
                    //用默认浏览器打开扫描得到的地址
                    Intent intent = new Intent();
                    intent.setAction("android.intent.action.VIEW");
                    Uri content_url = Uri.parse(result.toString());
                    intent.setData(content_url);
                    startActivity(intent);
                } else if (bundle.getInt(CodeUtils.RESULT_TYPE)
                        == CodeUtils.RESULT_FAILED) {
                    Toast.makeText(MainActivity.this, 
                            "解析二维码失败", Toast.LENGTH_LONG).show();}}}}}

   5.我们来看下运行效果吧
