I declared a RelativeLayout
in a xml layout file. Now I want to add Views
from code to the existing Layout. I added a Button
dynamically to this existing layout as below through code:
rLayout = (RelativeLayout)findViewById(R.id.rlayout);
LayoutParams lprams = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
Button tv1 = new Button(this);
tv1.setText("Hello");
tv1.setLayoutParams(lprams);
tv1.setId(1);
rLayout.addView(tv1);
Now I need to add another Button
to the right of the already added Button
. I am not able to find the way in which I can add the new one to the right of the previously added button.
Below that, the layout_height=0 and layout_weight=1 attributes on the RelativeLayout cause it to take up all the remaining space. You can then center the button in the RelativeLayout . You can play with padding on the button to get it to the size you want.
Positioning Views RelativeLayout lets child views specify their position relative to the parent view or to each other (specified by ID). So you can align two elements by right border, or make one below another, centered in the screen, centered left, and so on.
By default, all child views are drawn at the top-left of the layout, so you must define the position of each view using the various layout properties available from RelativeLayout.
Android RelativeLayout enables you to specify how child views are positioned relative to each other. The position of each view can be specified as relative to sibling elements or relative to the parent.
Add the rule RelativeLayout.RIGHT_OF
for the second added Button
LayoutParams
:
// first Button
RelativeLayout rLayout = (RelativeLayout) findViewById(R.id.rlayout);
RelativeLayout.LayoutParams lprams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
Button tv1 = new Button(this);
tv1.setText("Hello");
tv1.setLayoutParams(lprams);
tv1.setId(1);
rLayout.addView(tv1);
// second Button
RelativeLayout.LayoutParams newParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
Button tv2 = new Button(this);
tv1.setText("Hello2");
newParams.addRule(RelativeLayout.RIGHT_OF, 1);
tv2.setLayoutParams(newParams);
tv2.setId(2);
rLayout.addView(tv2);
may be this can help you, try it.
rLayout = (RelativeLayout)findViewById(R.id.rlayout);
LayoutParams lprams = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
TableLayout tl=new TableLayout(this);
rLayout.addView(tl);
TableRow tr1=new TableRow(this);
tl.addView(tr1);
Button btn1 = new Button(this);
btn1.setText("Hello");
btn1.setLayoutParams(lprams);
btn1.setId(1);
tr1.addView(btn1);
TextView tv1 = new TextView(this);
tv1.setWidth(40);
tv1.setHeight(LayoutParams.WRAP_CONTENT);
tr1.addView(tv1);
Button btn2 = new Button(this);
btn2.setText("World");
btn2.setLayoutParams(lprams);
btn2.setId(2);
tr1.addView(btn2);
