Question

iam在Android中真的很新，并得到了一些问题：

我有一些TableLayout，在这里我想动态添加一些行。行必须看起来一样，所以我在xml中编写了一个模板，并将其作为视图添加到行中。

在这个xml文件中，有一些TextViews，现在我想在每个TableRow中更改这些TextViews的Text，以便每个表行都有其他文本，如星期日，星期一等。

后来我想从数组中添加这个Text。

TableLayoute xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/SPone_RL1"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" 
android:background="@drawable/backrepeat"
android:layout_gravity="center_vertical">

 <ImageView
          android:id="@+id/SPone_RL_ImageView1"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:contentDescription="@drawable/logo"
          android:layout_centerInParent="true"
            />

<ScrollView 
    android:id="@+id/SPone_RL_SV"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" >

<RelativeLayout
    android:id="@+id/SPone_RL_SV_RL"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <TableLayout android:id="@+id/SPoneTable"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:padding="10dip" android:stretchColumns="*">

        </TableLayout>

 </RelativeLayout>

</ScrollView>
</RelativeLayout>

The Row xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

<RelativeLayout 
        android:id="@+id/SPone_RL_SV_RL_RL"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

      <LinearLayout
            android:id="@+id/SPone_RL_SV_RL_RL_LL1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
             >

            <LinearLayout
                android:layout_width="30dp"
                android:layout_height="match_parent"
                android:orientation="vertical" 
                android:layout_marginLeft="20dp">

                <TextView
                    android:id="@+id/textView1"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="12"

            </LinearLayout>

            <LinearLayout

Java代码：

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


    /* Find Tablelayout defined in main.xml */
 TableLayout tl = (TableLayout) findViewById(R.id.SPoneTable);


    for(int i = 0; i < 10; i++) {

        /* Create a new row to be added. */
        TableRow tr = new TableRow(this);
        tr.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
        /* Create a View to be the row-content. */
        LayoutInflater layoutInflater = (LayoutInflater) 
                this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
                //das Layout das 10 mal rein soll
                ViewGroup yourview = (ViewGroup)layoutInflater.inflate(R.layout.spielplantablerow, null);



        /* Add View to row. */
        tr.addView(yourview);
        /* Add row to TableLayout. */
        tr.setBackgroundResource(R.drawable.baggroundtable);
        tl.addView(tr, new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT));





    }
}

任何人都可以帮助我每次如何设置其他文本，也许是其中一个TextViews？没有从Java生成整个TextView？

Answer 1

只需获取对TextView的引用并编辑如下文本：

TextView tv = (TextView) yourview.findViewById(R.id.textViewID); // if your TextView is in yourview. If not, change it.
tv.setText("Your text or text resource");

在动态添加的行中更改文本
