Apply xml attribute to view in java code

Postby agent00 » Fri Jan 18, 2008 5:17 pm

Hi everybody,

I'm looking for a way to apply some attributes in my views but without using xml file.

Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1. <LinearLayout
  2.   id="@+id/widget25"
  3.   android:layout_width="fill_parent"
  4.   android:layout_height="wrap_content"
  5.   xmlns:android="http://schemas.android.com/apk/res/android"
  6.   >
  7.  
  8. <AnalogClock
  9.   id="@+id/widget28"
  10.   android:layout_width="50px"
  11.   android:layout_height="50px"
  12.   android:layout_gravity="center_vertical"
  13.   />
  14.  
  15. <TimePicker
  16.   id="@+id/widget29"
  17.   android:layout_width="wrap_content"
  18.   android:layout_height="wrap_content"
  19.   android:layout_gravity="center_vertical"
  20.   />
  21.  
  22. </LinearLayout>
Parsed in 0.001 seconds, using GeSHi 1.0.8.4

Here is the XML code of what i'm trying to do in java. Mainly the android:layout_gravity="center_vertical" of the time picker and the android:layout_width="fill_parent" of the linear layout.

Anyone can help me ?

Thanks

Regards, Agent00

Hello agent00,

this should help you further:
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.         LinearLayout linLay = (LinearLayout)findViewById(R.id.theLinearlayout);
  2.         linLay.setGravity(Gravity.CENTER_VERTICAL);
  3.         linLay.setLayoutParams(new LinearLayout.LayoutParams(
  4.                         LayoutParams.FILL_PARENT, // Width
  5.                         LayoutParams.FILL_PARENT) // Height
  6.                 );
Parsed in 0.011 seconds, using GeSHi 1.0.8.4

Hello Agent00,

please post the relevant code :) .

Do you really have to set the size of the ImageView explicitly :?: I don't know your program but the Layouts should manage resizing and stuff, perhaps it's better to add a attribute for automatic-resizing.
:idea: Width and Height of a View are defined using the LayoutParams as done above.
