在我的项目中,我设法以编辑文本和文本视图的行和列的形式显示数据库。但是随着行数和列数的增加,无法查看增加的数据,他们不适合在屏幕上。 所以我想我需要一个水平滚动视图和垂直滚动视图来查看整个行和列。 以下是我的代码,请帮助我如何实现这一点。 请你帮我在此先感谢动态创建水平和垂直滚动视图Android
XML代码
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TableLayout
android:layout_width="wrap_content"
android:stretchColumns="0,1,2,3,4,5"
android:id="@+id/maintable"
android:layout_height="wrap_content"
android:layout_weight="1.0">
</TableLayout>
</LinearLayout>
下面是我想展示我的行和列的网页代码
public class ViewActivity extends Activity {
EditText col1;
EditText col2;
TextView Id;
EditText col4;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view);
ScrollView sv = new ScrollView(this);
HorizontalScrollView hs =new HorizontalScrollView(this);
TableLayout tl = (TableLayout) findViewById(R.id.maintable);
//CREATING A LIST OF HEADINGS
TableRow tr1 = new TableRow(this);
tr1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
Id = new TextView(this);
Id.setText("COL1");
tr1.addView(Id);
Id = new TextView(this);
Id.setText("COL2");
tr1.addView(Id);
Id = new TextView(this);
Id.setText("COL3");
tr1.addView(Id);
Id = new TextView(this);
Id.setText("Rssi");
tr1.addView(COL4);
Id = new TextView(this);
Id.setText("Delete");
tr1.addView(COL5);
Id = new TextView(this);
Id.setText("Update");
tr1.addView(COL6);
hs.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
tl.addView(tr1,new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
// CREATING ROWS AND COLUMNS DYNAMICALLY
final DBclass entry = new DBclass(ViewActivity.this);
entry.open();
Cursor c = entry.getAllRecords();
int count =0;
if(c.moveToFirst()){
do{
TableRow tr = new TableRow(this);
tr.setId(count);
tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
/* CODE FOR
COLUMNS DISPLAYED IN THE FORM OF
EDITTEXTS AND TEXTVIEWS
*/
tl.addView(tr, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
count++;
}while(c.moveToNext());
}
}
