如何在Android中为Tablelayouts设置文本？

Question

I'm trying to set some values to text views in a table layout, but I can't test it on my phone due to self-closing the app.

My XML file is defined here:

 <TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tableAfc"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:stretchColumns="1">
   <TableRow
       android:id="@+id/rowAf1"
   >
     <TextView
         android:text="Litera"
         android:singleLine="true"
        android:id="@+id/tAf1"
        android:padding="5dip" />
    <TextView
        android:text="Pozitie initiala"
        android:singleLine="true"
        android:id="@+id/tAf2"
        android:gravity="center"
        android:padding="5dip" />
    <TextView
        android:text="Pozitie mediana"
        android:id="@+id/tAf3"
        android:singleLine="true"
        android:gravity="center"
        android:padding="5dip" />
     <TextView
        android:text="Pozitie finala"
        android:singleLine="true"
        android:id="@+id/tAf4"
        android:gravity="center"
        android:padding="5dip" />
    </TableRow>
  </TableLayout>

My java code...

 public void onCreate(Bundle icicle) {
       super.onCreate(icicle);
       setContentView(R.layout.cons_africate);
       TextView t1= (TextView) super.findViewById(R.id.tAf1);
       t1.setText(1);
   }

If I don't try to change the text in the java code, it works, but with those two lines it crashes...

Answer 1

t1.setText(1); does not work because setText() only accept CharSquence type. So use t1.setText("1");

Answer 2

在settext中使用倒置逗号，即“ 1”
