Question

我正在尝试使用com.google.zxing.client.android.SCAN扫描二维码，但它没有打开相机并始终以“扫描已取消！”进行响应仅限Sony Xperia C的Toast消息。

ScanQR.java

ScanBtn.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        try {
            Intent intent = new Intent(
                    "com.google.zxing.client.android.SCAN");
            intent.putExtra("SCAN_MODE", "QR_CODE_MODE");

            startActivityForResult(intent, 0);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

  });

 }

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
    if (resultCode == RESULT_OK) {
        String contents = intent.getStringExtra("SCAN_RESULT");
        String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
        // Handle successful scan

        Toast toast = Toast.makeText(this, "Content:" + contents,
                Toast.LENGTH_LONG);
        toast.setGravity(Gravity.TOP, 25, 400);
        toast.show();

    } else if (resultCode == RESULT_CANCELED) {
        // Handle cancel
        Toast toast = Toast.makeText(this, "Scan was Cancelled!",
                Toast.LENGTH_LONG);
        toast.setGravity(Gravity.TOP, 25, 400);
        toast.show();

    }
}
}

的manifest.xml

     <?xml version="1.0" encoding="utf-8"?>
     <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.test"
    android:versionCode="1"

        <activity
            android:name="com.example.test.ScanQR"
            android:configChanges="orientation|keyboardHidden"
            android:label="@string/app_name"
            android:windowSoftInputMode="stateAlwaysHidden" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

   </manifest>

尝试这样的事情。 startActivityForResult（新意图（ Emailtry.this， com.google.zxing.client.android.CaptureActivity.class） 11）;
