Question

我是Android Native Development的新手，我想在警告消息中显示“在浏览器中打开”图标。

Case: 
I have a QR code scanned and showing the result in a toast or Alert. 
In the scanned Result, I want to Show up "Open In Browser" with the code result or Alert message

挑战是我无法实现此功能。请让我知道如何做到这一点，以便我可以进一步学习Android。

My Manifest goes like this:

 <uses-permission android:name="android.permission.CAMERA" />


    <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">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>



And my Result handler
   @Override
    public void handleResult(Result rawResult) {
        // Do something with the result here
        Log.v("TAG", rawResult.getText()); // Prints scan results
        Log.v("TAG", rawResult.getBarcodeFormat().toString()); // Prints the scan format (qrcode, pdf417 etc.)
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
                builder.setTitle("UTQode Result");
                builder.setMessage(rawResult.getText());
                AlertDialog alert1 = builder.create();
                alert1.show();
//        Toast.makeText(getApplicationContext(), "My Message",
//                Toast.LENGTH_SHORT).show();
        Toast.makeText(this, rawResult.getText(), Toast.LENGTH_LONG).show();

        // If you would like to resume scanning, call this method below:
        mScannerView.resumeCameraPreview(this);
    }

I am testing with the above code, but I need to open the alert result and Query it in Browser

在警告对话框中执行此操作：

AlertDialog.Builder builder = new AlertDialog.Builder(this);
                builder.setTitle("UTQode Result");
                builder.setMessage(rawResult.getText());
                builder..setIcon(getResources().getDrawable(android.R.drawable.your_icon));
                AlertDialog alert1 = builder.create();
                alert1.show();

如果您想要一个“在浏览器中打开”文本的按钮，请执行以下操作：

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
                        builder.setTitle("UTQode Result");
                        builder.setMessage(rawResult.getText());
                        builder.setIcon(getResources().getDrawable(android.R.drawable.your_icon));
    builder.setPositiveButton("Open in browser", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                    //do things
                    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(your result url)));
               }
           });
                        AlertDialog alert1 = builder.create();
                        alert1.show();

如果要通过单击“在浏览器中打开”打开浏览器，可以按下按钮添加方法

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
            context);

        // set title
        alertDialogBuilder.setTitle("Your Title");

        // set dialog message
        alertDialogBuilder
            .setMessage("Click yes to exit!")
            .setCancelable(false)
            .setPositiveButton("Open in Browser",new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog,int id) {
                    openInBrowser();
                }
              })
            .setNegativeButton("No",new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog,int id) {
                    // if this button is clicked, just close
                    // the dialog box and do nothing
                    dialog.cancel();
                }
            });

            // create alert dialog
            AlertDialog alertDialog = alertDialogBuilder.create();

            // show it
            alertDialog.show();

如果您只想在警报顶部使用图标，请使用.setIcon（）

Android Show在浏览器中打开警报
