问题描述

我在我的应用程序，我试着以测试功能的子片段。我们的想法是，该TextView的将更新，以模仿无论是进入的EditText。但是目前它不喜欢的setText，我不知道为什么。我检查，看看是否我已经错过了进口，我认为小部件正确定义。如何解决这个问题的任何意见将是巨大的。

TextView的标签=（TextView中）getActivity（）findViewById（R.id.weightResult）。。字符串结果= weight.getText（）的toString（）;
label.setText（结果）;}
 

解决方案

把code里面的方法，如：

  @覆盖
公共查看onCreateView（LayoutInflater充气器，容器的ViewGroup，
                         捆绑savedInstanceState）{
    查看rootView = inflater.inflate（R.layout.fragment_weight，集装箱，FALSE）;    重量的EditText =（EditText上）getActivity（）findViewById（R.id.weightInput）。
    TextView的标签=（TextView中）getActivity（）findViewById（R.id.weightResult）。    。字符串结果= weight.getText（）的toString（）;
    label.setText（结果）;
    返回rootView;
}
 

I have a child fragment in my application that im trying to test functionality in. The idea is that the textview will update to mimic whatever is entered into the edittext. However currently it doesn't like the setText and i have no idea why. I've checked to see whether i had missed an import and i think the widgets are defined correctly. Any advice on how to solve this problem would be great.

import com.actionbarsherlock.app.SherlockFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.EditText;
import android.widget.TextView;

public class WeightFragment extends SherlockFragment {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_weight, container, false);
    return rootView;
}

EditText weight = (EditText) getActivity().findViewById(R.id.weightInput);
TextView label = (TextView) getActivity().findViewById(R.id.weightResult);

String result = weight.getText().toString();
label.setText(result);

}

解决方案

Put the code INSIDE a method, like this:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_weight, container, false);

    EditText weight = (EditText) getActivity().findViewById(R.id.weightInput);
    TextView label = (TextView) getActivity().findViewById(R.id.weightResult);

    String result = weight.getText().toString();
    label.setText(result);
    return rootView;
}
