Question

这是我的片段代码，当它不起作用时没有错误放置！每个片段都有语音识别按钮，inputText接收文本，给定文本与inputText进行比较，如果不匹配则突出显示为红色，

public class LayoutOne extends Fragment {

protected static final int RESULT_SPEECH = 1;

private ImageButton btnSpeak;
private TextView inputText;
    private TextView givenText;

public static Fragment newInstance(Context context) {
    LayoutOne f = new LayoutOne();  

    return f;
}

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.layout_one);

    inputText = (TextView)getView().findViewById(R.id.inputText);
    givenText = (TextView)getView().findViewById(R.id.givenText);
    btnSpeak = (ImageButton)getView().findViewById(R.id.btnSpeak);
    btnSpeak.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
            intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
            try{
                startActivityForResult(intent, RESULT_SPEECH);
                inputText.setText("");
            }catch(ActivityNotFoundException a) { 

            }
        }
    });
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
    ViewGroup v = (ViewGroup) inflater.inflate(R.layout.layout_one, null);

    return v;
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
    case RESULT_SPEECH: {
        if (resultCode == -1 && null != data) {

            ArrayList<String> text = data
                    .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            inputText.setText(text.get(0));
            if(givenText.getText().toString().equalsIgnoreCase(inputText.getText().toString())){

                inputText.setBackgroundColor(Color.parseColor("BLUE"));
            }
            else{

                {inputText.setBackgroundColor(Color.parseColor("RED"));}
            }
        }
        break;
       }
     } 
   }
 }

任何想法？

首先你需要以不同的方式创建你的片段类，因为你没有inflater，片段没有使用泛型onCreate作为其他android类......

Public class myFragment extends Fragment{

TextView testTextView;
View myFragmentView
    public View onCreateView(LayoutInflater viewInflation, ViewGroup container,
            Bundle SavedInstantState) {

        myFragmentView = viewInflation.inflate(
                R.layout.myfragment_layout, container, false);
            testTextView = myFragmentView.findViewById(R.id.testTextView);
   }
}

这是如何设置片段的基本示例....然后，您可以使用事务管理器在FragmentActivity中对其进行充气，并创建Fragment类的字段。< / p>

另外，如果您使用eclipse的可视化编辑器，您只需从可视菜单中拖放一个片段，它应该只询问您想要附加到哪个片段类。

片段活动不起作用
