我正在創建一個新的android application.i使用表格佈局。我編碼如下，但是當我運行該程序時，它顯示強制關閉程序。 任何人可以幫助這個代碼。java中的表格佈局
public class SongsActivity extends Activity{
DemoView demoview ;
DemoView2 finalview;
DemoView3 dview;
DemoView4 deview;
ViewFlipper c ;
TableLayout d;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.songs_layout);
demoview = new DemoView(this);
finalview = new DemoView2(this);
dview= new DemoView3(this);
deview = new DemoView4(this);
d= new TableLayout(this);
c=(ViewFlipper)findViewById(R.id.viewFlipper1);
c.addView(demoview,0);
c.addView(finalview, 1);
c.addView(dview, 2);
c.addView(deview, 3);
c.setAutoStart(true);
c.setFlipInterval(500);
c.startFlipping();
TableRow rw1=new TableRow(this);
TableRow rw2=new TableRow(this);
TableRow.LayoutParams params = new TableRow.LayoutParams();
params.span = 6;
rw1.addView(c);
rw2.addView(c);
d.addView(rw2);
d.addView(rw1);
setContentView(d);
}
我的佈局認定中是遵循
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1">
<TableRow
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/tableRow1">
<!-- Screen Design for the SONGS -->
<ViewFlipper android:id="@+id/viewFlipper1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ViewFlipper>
</TableRow>
<TableRow
android:orientation="vertical"
android:id="@+id/tableRow2"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TableRow>
</TableLayout>
我logcat的是顯示以下錯誤
