二维码扫描扫描到网址跳转到wenView中
上代码：
compile 'com.journeyapps:zxing-android-embedded:3.3.0'
1 设置一个按钮跳转界面：
调用：
public void customScan(){ new IntentIntegrator(this) .setOrientationLocked(false) .setCaptureActivity(CustomScanActivity.class) // 设置自定义的activity是CustomActivity .initiateScan(); // 初始化扫描 }
用OnActivityResult接收
@Override // 通过 onActivityResult的方法获取 扫描回来的 值 protected void onActivityResult(int requestCode, int resultCode, Intent data) { IntentResult intentResult = IntentIntegrator.parseActivityResult(requestCode,resultCode,data); if(intentResult != null) { if(intentResult.getContents() == null) { Toast.makeText(this,"内容为空",Toast.LENGTH_LONG).show(); } else { String ScanResult = intentResult.getContents(); getResult(ScanResult); } } else { super.onActivityResult(requestCode,resultCode,data); } }
对结果进行判断：
/** * 对结果进行判断，如果是http开头的，就跳转到webview * @param result * || str1 == "www" || str1 == "WWW" */ private String str; private String str1; public void getResult(String result){ //0 到 4 ，截取的时候是包括左边（0），不包括右边（4），所以是0,1,2,3 前四个。 String str = result.substring(0,4); String str1 = result.substring(0,3); if ("http".equals(str) || "WWW".equals(str1) || "www".equals(str1)) { Intent intent = new Intent(MainActivity.this,WebActivity.class); intent.putExtra("url",result); startActivity(intent); }else if("OMI".equals(str1)){ Toast.makeText(MainActivity.this,"OMI",Toast.LENGTH_SHORT).show(); }else{ Toast.makeText(MainActivity.this,"qita",Toast.LENGTH_SHORT).show(); } text.setText(result); }
这个界面的布局：
xml version="1.0" encoding="utf-8"?>
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@color/white"
>
2 第二个界面：
扫描界面：
CustomScanActivity
package com.example.administrator.eitherdemo1; import android.content.pm.PackageManager; import android.os.Bundle; import android.os.PersistableBundle; import android.support.v7.app.AppCompatActivity; import android.view.KeyEvent; import android.view.View; import android.view.Window; import android.widget.Button; import com.journeyapps.barcodescanner.CaptureManager; import com.journeyapps.barcodescanner.DecoratedBarcodeView; /** * Created by Administrator on 2017/4/7 0007. */ public class CustomScanActivity extends AppCompatActivity implements DecoratedBarcodeView.TorchListener{ // 实现相关接口 // 添加一个按钮用来控制闪光灯，同时添加两个按钮表示其他功能，先用Toast表示 Button swichLight; DecoratedBarcodeView mDBV; private CaptureManager captureManager; private boolean isLightOn = false; public CustomScanActivity instance; public CustomScanActivity getInstance(){ if(instance == null){ instance = new CustomScanActivity(); } return instance; } @Override protected void onPause() { super.onPause(); captureManager.onPause(); } @Override protected void onResume() { super.onResume(); captureManager.onResume(); } @Override protected void onDestroy() { super.onDestroy(); captureManager.onDestroy(); finish(); } @Override public void onSaveInstanceState(Bundle outState, PersistableBundle outPersistentState) { super.onSaveInstanceState(outState, outPersistentState); captureManager.onSaveInstanceState(outState); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { return mDBV.onKeyDown(keyCode, event) || super.onKeyDown(keyCode, event); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_custom); initView(); mDBV.setTorchListener(this); // 如果没有闪光灯功能，就去掉相关按钮 if(!hasFlash()) { swichLight.setVisibility(View.GONE); } //重要代码，初始化捕获 captureManager = new CaptureManager(this,mDBV); captureManager.initializeFromIntent(getIntent(),savedInstanceState); captureManager.decode(); } //初始化控件 Button swichLight,hintlShow,hint2Show; private void initView() { mDBV = (DecoratedBarcodeView) findViewById(R.id.dbv_custom); swichLight = (Button) findViewById(R.id.btn_switch); swichLight.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { getswichLight(); } }); } // torch 手电筒 @Override public void onTorchOn() { isLightOn = true; } @Override public void onTorchOff() { isLightOn = false; } private boolean hasFlash() { return getApplicationContext().getPackageManager() .hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH); } // 点击切换闪光灯 public void getswichLight(){ if(isLightOn){ mDBV.setTorchOff(); }else{ mDBV.setTorchOn(); } } }
布局时：
xml version="1.0" encoding="utf-8"?>
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
>
3 需要用到自定义的扫描界面：
app:zxing_scanner_layout="@layout/barcode_scanner"需要自己去创建：
xml version="1.0" encoding="utf-8"?>
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
>
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/zxing_barcode_surface"
app:zxing_framing_rect_width="250dp"
app:zxing_framing_rect_height="250dp">
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/zxing_viewfinder_view"
app:zxing_possible_result_points="@color/zxing_custom_possible_result_points"
app:zxing_result_view="@color/zxing_custom_result_view"
app:zxing_viewfinder_laser="#FFFFFF"
app:zxing_viewfinder_mask="@color/zxing_custom_viewfinder_mask"/>
android:id="@+id/zxing_status_view"
android:layout_width="wrap_content"
android:layout_height="44dp"
android:layout_gravity="bottom|center_horizontal"
android:layout_above="@id/zxing_viewfinder_view"
android:background="@color/zxing_transparent"
android:text="@string/zxing_msg_default_status"
android:textColor="@color/zxing_status_text" />
对应的
CustomViewfinderView
需要自己定义：
package com.example.administrator.eitherdemo1; /** * Created by Administrator on 2017/4/7 0007. */ import android.content.Context; import android.graphics.Canvas; import android.graphics.LinearGradient; import android.graphics.Rect; import android.graphics.Shader; import android.util.AttributeSet; import com.google.zxing.ResultPoint; import com.journeyapps.barcodescanner.ViewfinderView; import java.util.ArrayList; import java.util.List; /** * 自定义zxing二维码扫描界面 * Created by IBM on 2016/10/20. */ public class CustomViewfinderView extends ViewfinderView { public int laserLinePosition=0; public float[] position=new float[]{0f,0.5f,1f}; public int[] colors=new int[]{0x00ffffff,0xffffffff,0x00ffffff}; public LinearGradient linearGradient ; public CustomViewfinderView(Context context, AttributeSet attrs) { super(context, attrs); } /** * 重写draw方法绘制自己的扫描框 * @param canvas */ @Override public void onDraw(Canvas canvas) { refreshSizes(); if (framingRect == null || previewFramingRect == null) { return; } Rect frame = framingRect; Rect previewFrame = previewFramingRect; int width = canvas.getWidth(); int height = canvas.getHeight(); //绘制4个角 paint.setColor(0xFFFFFFFF);//定义画笔的颜色 canvas.drawRect(frame.left, frame.top, frame.left+70, frame.top+10, paint); canvas.drawRect(frame.left, frame.top, frame.left + 10, frame.top + 70, paint); canvas.drawRect(frame.right-70, frame.top, frame.right, frame.top+10, paint); canvas.drawRect(frame.right-10, frame.top, frame.right, frame.top+70, paint); canvas.drawRect(frame.left, frame.bottom-10, frame.left+70, frame.bottom, paint); canvas.drawRect(frame.left, frame.bottom-70, frame.left+10, frame.bottom, paint); canvas.drawRect(frame.right-70, frame.bottom-10, frame.right, frame.bottom, paint); canvas.drawRect(frame.right-10, frame.bottom-70, frame.right, frame.bottom, paint); // Draw the exterior (i.e. outside the framing rect) darkened paint.setColor(resultBitmap != null ? resultColor : maskColor); canvas.drawRect(0, 0, width, frame.top, paint); canvas.drawRect(0, frame.top, frame.left, frame.bottom + 1, paint); canvas.drawRect(frame.right + 1, frame.top, width, frame.bottom + 1, paint); canvas.drawRect(0, frame.bottom + 1, width, height, paint); if (resultBitmap != null) { // Draw the opaque result bitmap over the scanning rectangle paint.setAlpha(CURRENT_POINT_OPACITY); canvas.drawBitmap(resultBitmap, null, frame, paint); } else { // paint.setAlpha(SCANNER_ALPHA[scannerAlpha]); // scannerAlpha = (scannerAlpha + 1) % SCANNER_ALPHA.length; int middle = frame.height() / 2 + frame.top; laserLinePosition=laserLinePosition+5; if(laserLinePosition>frame.height()) { laserLinePosition=0; } linearGradient= new LinearGradient(frame.left + 1, frame.top+laserLinePosition , frame.right -1 , frame.top +10+laserLinePosition, colors, position, Shader.TileMode.CLAMP); // Draw a red "laser scanner" line through the middle to show decoding is active // paint.setColor(laserColor); paint.setShader(linearGradient); //绘制扫描线 canvas.drawRect(frame.left + 1, frame.top+laserLinePosition , frame.right -1 , frame.top +10+laserLinePosition, paint); paint.setShader(null); float scaleX = frame.width() / (float) previewFrame.width(); float scaleY = frame.height() / (float) previewFrame.height(); ListcurrentPossible = possibleResultPoints; List currentLast = lastPossibleResultPoints; int frameLeft = frame.left; int frameTop = frame.top; if (currentPossible.isEmpty()) { lastPossibleResultPoints = null; } else { possibleResultPoints = new ArrayList<>(5); lastPossibleResultPoints = currentPossible; paint.setAlpha(CURRENT_POINT_OPACITY); paint.setColor(resultPointColor); for (ResultPoint point : currentPossible) { canvas.drawCircle(frameLeft + (int) (point.getX() * scaleX), frameTop + (int) (point.getY() * scaleY), POINT_SIZE, paint); } } if (currentLast != null) { paint.setAlpha(CURRENT_POINT_OPACITY / 2); paint.setColor(resultPointColor); float radius = POINT_SIZE / 2.0f; for (ResultPoint point : currentLast) { canvas.drawCircle(frameLeft + (int) (point.getX() * scaleX), frameTop + (int) (point.getY() * scaleY), radius, paint); } } postInvalidateDelayed(16, frame.left , frame.top , frame.right , frame.bottom); // postInvalidate(); } } }
webView 界面就不写了，请注意使用webView一定要加联网权限。
