zxing onActivityResult不叫的片段只在活动只在、不叫、片段、zxing

2023-09-05 06:58:30 作者：安於現狀°づ

我在使用zxing onActivityResult（）的一些问题。

正如你可以在code见我没有正确地在https://$c$c.google.com/p/zxing/wiki/ScanningViaIntent.

现在的问题是我怎么能赶上onActivityResult（）的片段，因为我需要在我的Fragmnet而不是在活动这个数据？

I'm having some issue with zxing onActivityResult().

As you can see in the code I did properly invoke new intent as described in https://code.google.com/p/zxing/wiki/ScanningViaIntent.

The question is how can I catch onActivityResult() in Fragment, since I need this data in my Fragmnet and not in Activity?

package com.example.testingcodereading;

import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;

public class MainFragment extends Fragment {

private Button mButtonXZing;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle     savedInstanceState){
    View v = inflater.inflate(R.layout.fragment_main, parent, false);

    mButtonXZing = (Button) v.findViewById(R.id.button_xzing);
    mButtonXZing.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            IntentIntegrator integrator = new IntentIntegrator(getActivity());
            integrator.initiateScan();

        }
    });

    return v;
}


@Override 
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    System.out.println("never here");
      IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
      if (scanResult != null) {
        // handle scan result
      }
      // else continue with any other code you need in the method
    }

}

public class MainActivity extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

FragmentManager fm = getSupportFragmentManager();
Fragment f = fm.findFragmentById(R.id.fragmentContainer);

if(f == null){
  f = new MainFragment();
  fm.beginTransaction()
    .add(R.id.fragmentContainer, f)
    .commit();
}
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    System.out.println("the code is catch");
}

}

解决方案

If any one have the same issue here is my solution.

package com.example.testingcodereading;

import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;

public class MainActivity extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fragment);

FragmentManager fm = getSupportFragmentManager();
Fragment f = fm.findFragmentById(R.id.fragmentContainer);

if (f == null) {
  f = MainFragment.newInstance("Start Application");
  fm.beginTransaction().add(R.id.fragmentContainer, f).commit();
}
}

@Override
protected void onActivityResult(int requestCode, int resultCode,
  Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
System.out.println("the code is catch");

IntentResult scanResult = IntentIntegrator.parseActivityResult(
    requestCode, resultCode, intent);
// handle scan result
if (scanResult != null) {
  FragmentManager fm = getSupportFragmentManager();

  Fragment newFrame = MainFragment.newInstance(scanResult.toString());

  fm.beginTransaction().replace(R.id.fragmentContainer, newFrame).commit();
}

}

}

package com.example.testingcodereading;

import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.test.suitebuilder.annotation.MediumTest;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;

public class MainFragment extends Fragment {

private static final String EXTRA_CODE = "com.example.testingcodereading.code";
private Button mButtonXZing;
private TextView mTextView;


public static MainFragment newInstance(String code) {
Bundle args = new Bundle();
args.putSerializable(EXTRA_CODE, code);

MainFragment fragment = new MainFragment();
fragment.setArguments(args);

return fragment;
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle    savedInstanceState){
View v = inflater.inflate(R.layout.fragment_main, parent, false);

mTextView = (TextView) v.findViewById(R.id.text_code);
mTextView.setText((String) getArguments().getSerializable(EXTRA_CODE));

mButtonXZing = (Button) v.findViewById(R.id.button_xzing);
mButtonXZing.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {

    IntentIntegrator integrator = new IntentIntegrator(getActivity());
    integrator.initiateScan();
  }
});

return v;
}


@Override 
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
System.out.println("never here");
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (scanResult != null) {
  // handle scan result
}
// else continue with any other code you need in the method
}
