Question

您好，这是我的第一个问题情况就是这样：我正在制作一个带有特定按钮来扫描条形码的服装软键盘，它打开条形码扫描器，扫描后，它返回上一个屏幕（比如消息应用程序），结果是剪辑或共享偏好。所有精细和花花公子，除了EditText中的结果来自旧扫描而不是新扫描的事实，因为当第一个活动获得结果时此时扫描没有完成（在启动条形码扫描仪活动之前）我是尝试使用布尔测试在on键函数中使用handler.postDelayed等待扫描完成但是这会在启动扫描之前冻结活动，因为我没有响应错误关键功能是：

 case 2017:
            //Toast.makeText(FloatingViewService.this, "NormalScan.", Toast.LENGTH_LONG).show();
            test=true;
            InputConnection ic  = getCurrentInputConnection();
            ic.deleteSurroundingText(100, 100);  //pour vider le champs de saisair
            Intent dialogIntent = new Intent(SimpleIME.this, NormalScan.class);
            dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity( dialogIntent);
            ic.commitText(String.valueOf(pref.getString("code", null)),1);

用于扫描条形码的NormalScan.class是：

public class NormalScan  extends AppCompatActivity {

    private ClipboardManager myClipboard;
    private ClipData myClip;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);


        IntentIntegrator integrator = new IntentIntegrator(this);
       // integrator.setOrientationLocked(false);
        integrator.setPrompt("Scan a barcode or QRcode");
        integrator.initiateScan();


        // integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
//        Use this for more customization
//integrator.setOrientationLocked(true);
//        IntentIntegrator integrator = new IntentIntegrator(this);

//        integrator.setDesiredBarcodeFormats(IntentIntegrator.ONE_D_CODE_TYPES);

//        integrator.setPrompt("Scan a barcode");

//        integrator.setCameraId(0);  // Use a specific camera of the device

//        integrator.setBeepEnabled(false);

//        integrator.setBarcodeImageEnabled(true);

//        integrator.initiateScan();

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);

使用startActivityForResult启动活动。调用onActivityResult时，保存扫描的条形码。下次建立inputConnection时，插入条形码 - 这应该是EditText的新连接

自定义键盘扫描条形码并将结果插入EditText
