LayoutInflater wordSpan

Question

我想在 OnCreateView 设置 wordtoSpan 字符串。

我的代码：

package com.tachles;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.text.Spannable;
import android.text.SpannableString;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class History_moadim_a extends Fragment {

    TextView horef;
    TextView kaiz;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.history_moadim_a, container, false);

        return rootView;

        horef = (TextView) findViewById(R.id.textView3);
        Spannable wordtoSpan = new SpannableString("hgh");
        horef.setText(wordtoSpan);



    }
}

Eclipse 说我不能使用 findViewById，所以我尝试插入 getView() 但仍然是同样的问题。请告诉我我的错误

谢谢

Answer 1

如果history_moadim_a 是包含textView3 的布局，请将onCreateView() 更改为类似

View rootView = inflater.inflate(R.layout.history_moadim_a, container, false);

horef = (TextView) rootView.findViewById(R.id.textView3);
Spannable wordtoSpan = new SpannableString("hgh");
horef.setText(wordtoSpan);

return rootView;

您想在刚刚膨胀的布局中找到TextView (rootView)，并在结束处返回布局（而不是在方法的中间）。

使用

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.text.Spannable;
import android.text.SpannableString;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class History_moadim_a extends Fragment {

    TextView horef;
    TextView kaiz;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.history_moadim_a, container, false);



        horef = (TextView) rootView.findViewById(R.id.textView3);
        Spannable wordtoSpan = new SpannableString("hgh");
        horef.setText(wordtoSpan);

 return rootView;

    }
}

我在完美的地方看不到 onCreateView 的返回语句，所以请在 onCreateView 的末尾通过 onCreateView 的方式在 onCreateView 中执行return rootView ;
