Java setText使我的应用程序崩溃

我不懂Android编程，也不懂网络，我不明白为什么我的应用程序在设置一个

TextView

的文本时会崩溃

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_result,
            container, false);
    nombre = (TextView) rootView.findViewById(R.id.textView2);
    edad = (TextView) rootView.findViewById(R.id.textView4);
    sex = (TextView) rootView.findViewById(R.id.textView6);
    return rootView;
}

我的第一个

活动是一个问题：

public class MainActivity extends ActionBarActivity {

private static Spinner spinner;
private static LinkedList<Integer> list;
private static EditText editText1, editText2;
private RadioGroup rG;
public ArrayList<String> info;

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

    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment()).commit();
    }

}

private static void ageSpinner(View v) {

    list = new LinkedList<Integer>();

    for (Integer i = 0; i <= 110; i++) {

        list.add(i);

    }

    ArrayAdapter<Integer> spinnerAdapter = new ArrayAdapter<Integer>(
            v.getContext(), android.R.layout.simple_spinner_item, list);
    spinnerAdapter
            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    spinner.setAdapter(spinnerAdapter);

}

public void goResult(View v) {

    info = new ArrayList<String>();

    editText1 = (EditText) findViewById(R.id.editText1);
    editText2 = (EditText) findViewById(R.id.editText2);

    info.add(editText1.getText().toString());

    info.add(editText2.getText().toString());

    rG = (RadioGroup) findViewById(R.id.radioGroup1);
    int select = rG.getCheckedRadioButtonId();

    if (select == R.id.radio0) {

        info.add("Male");

    } else {
        info.add("Female");
    }

    info.add(spinner.getSelectedItem().toString());

    Intent i = new Intent(this, Result.class);

    i.putExtra("miki", info);
    startActivity(i);

}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

/**
 * A placeholder fragment containing a simple view.
 */
public static class PlaceholderFragment extends Fragment {

    public PlaceholderFragment() {
    }

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

        spinner = (Spinner) rootView.findViewById(R.id.spinner1);
        ageSpinner(rootView);

        return rootView;
    }
}

}

有什么想法吗

谢谢
 在
getResult
中有一个
NullPointerException
（可能是因为对
findViewById
的所有调用都返回
Null
）

您可能已经在片段XML中声明了UI组件（
TextView
等），并试图从
R.layout.activity\u result
检索它，反之亦然。检查您是否已在
R.layout.fragment\u main
中声明了UI组件，并从
onCreateView
中检索它们

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_result,
            container, false);
    nombre = (TextView) rootView.findViewById(R.id.textView2);
    edad = (TextView) rootView.findViewById(R.id.textView4);
    sex = (TextView) rootView.findViewById(R.id.textView6);
    return rootView;
}

首先，在
main活动中
在
Intent
中添加
ArrayList
，如下所示：

Intent i = new Intent(this, Result.class);
i.putStringArrayListExtra("miki", info);
startActivity(i);

在您的
Result
活动中，调用您的
getResult（）
条件如下，则在
之前使用code>方法：

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

        getResult();
    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment()).commit();
    }
}

发布您的logcat错误。尝试将此
b.putStringArrayList（“miki”，info）；
添加到您的BundleInwich布局文件中您是否声明了UI组件？很高兴提供帮助：）@j4m3s0n
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_result);

        getResult();
    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment()).commit();
    }
}
