Java 如何在片段中动态添加TableRow？

我是Android编程新手，目前我正在尝试在表布局中动态地插入一个文本视图片段。它在将课堂扩展到活动时起了作用。下面是我的代码片段。我错过什么了吗

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_schedule, null);
    TableLayout ll = (TableLayout) getActivity().findViewById(R.id.tableLayout1);
    TableRow tr= new TableRow(getActivity());
    TextView tv1 = new TextView(getActivity());
    tv1.setText("TEST NUMBER");
    tv1.setTextColor(Color.WHITE);
    tv1.setTextSize(20);
    tv1.setPadding(5, 5, 5, 5);
    tr.addView(tv1);
    ll.addView(tr);
    return view;
}

提前谢谢。

• 代码中的内容：：背景和文本颜色相同，因此无法查看文本
• 解决方案：：更改文本颜色或背景

我进行了如下测试

活动\u main.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

</FrameLayout>

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/table"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

</TableLayout>

fragmentOne.java

package com.example.test;

import android.graphics.Color;
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.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;


public class fragmentOne extends Fragment{

    public static fragmentOne newInstance(){
        fragmentOne fragment = new fragmentOne();
        return  fragment;
    }

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

        View view=inflater.inflate(R.layout.fragment_main, container, false);
        TableLayout ll = (TableLayout) view.findViewById(R.id.table);
        TableRow tr= new TableRow(getActivity());
        TextView tv1 = new TextView(getActivity());
        tv1.setText("TEST NUMBER");
        tv1.setTextColor(Color.BLACK);
        tv1.setTextSize(20);
        tv1.setPadding(5, 5, 5, 5);
        tr.addView(tv1);
        ll.addView(tr);
        return view;
    }

}

您必须给出view.findViewById， 因为您要在视图中添加它

TableLayout ll = (TableLayout) view.findViewById(R.id.tableLayout1);

检查它肯定会对您有所帮助。

这对我很有用：

@Override
public View onCreateView(LayoutInflater inf, ViewGroup container, Bundle state) {

    View view = inf.inflate(R.layout.records_fragment, container, false);

    TableLayout table = (TableLayout) view.findViewById(R.id.records);

    // Do something with the table declare in fragment.
    return view;
}

您是否面临上述代码的任何问题？

@Override
public View onCreateView(LayoutInflater inf, ViewGroup container, Bundle state) {

    View view = inf.inflate(R.layout.records_fragment, container, false);

    TableLayout table = (TableLayout) view.findViewById(R.id.records);

    // Do something with the table declare in fragment.
    return view;
}
