将TableRows动态添加到片段

Question

我试图向我的动态创建的TableLayout添加一些随机数据，以查看它是否正常工作。

下面是代码

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.RelativeLayout; 
import android.widget.TableLayout; 
import android.widget.TableRow; 
import android.widget.TableRow.LayoutParams; 
import android.widget.TextView; 

public class BasicDetailsTabFragment extends Fragment 
{ 
    int numvals = 5; 
    public static final int NAME = 0; 
    public static final int BRANCH = 1; 
    public static final int EMAIL = 2; 
    public static final int REGISTRATION = 3; 
    public static final int ADMISSION = 4; 

    String[] details = new String[5]; 
    String[] detailVals = new String[5]; // Get the values from JSON here 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
    { 
     if (container == null) 
     { 
      return null; 
     } 

     details[NAME] = "Name"; 
     details[BRANCH] = "Branch"; 
     details[EMAIL] = "Email"; 
     details[REGISTRATION] = "Registration No."; 
     details[ADMISSION] = "Admission No. "; 

     detailVals[NAME] = "Some Name"; 
     detailVals[BRANCH] = "Computer Science"; 
     detailVals[EMAIL] = "some_email@email.com"; 
     detailVals[REGISTRATION] = "11101212"; 
     detailVals[ADMISSION] = "1345645"; 

     View view = inflater.inflate(R.layout.basic_details_layout, 
     container, false); 

     TableLayout tl = (TableLayout)view.getView().findViewById(R.id.detailsTable); 

     for (int i = 0; i < numvals; i++) 
     { 
      // Make TR 
      TableRow tr = new TableRow(getActivity()); 
      tr.setId(100 + i); 
      tr.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); 

      // Make TV to hold the details 
      TextView detailstv = new TextView(getActivity()); 
      detailstv.setId(200 + i); 
      detailstv.setText(details[i]); 
      tr.addView(detailstv); 

      // Make TV to hold the detailvals 

      TextView valstv = new TextView(getActivity()); 
      valstv.setId(300 + i); 
      valstv.setText(detailVals[i]); 
      tr.addView(valstv); 

      tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); 
     } 

     return (RelativeLayout) inflater.inflate(R.layout.basic_details_layout, container, false); 

    } 

这里是布局的XML此类

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

    <ImageView 
     android:id="@+id/studentPhoto" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="15dp" 
     android:src="@drawable/student_photo" /> 

    <TableLayout 
     android:id="@+id/detailsTable" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_below="@id/studentPhoto" > 
    </TableLayout> 

</RelativeLayout> 

这种方法却行不通（显示除了照片是Nothing） 我一个相对的初学者在使用片段，我也困惑的是其中函数（onCreate（），onCreateActivity（）等）我应该把上面的代码填充我的表。

任何帮助表示赞赏。

如果我的问题看起来过于愚蠢，我很抱歉。

而不是第二次膨胀basic_details_layout，返回您已经膨胀的视图。

return (RelativeLayout) inflater.inflate(R.layout.basic_details_layout, container, false); 

应该

return view;
