Menu
I try to make an application, where the user can set a "one hand layout" for big devices to input the numbers with only one hand. (See the image for what I am meaning)
When I press on "L" the layout turns to left. This is working. But after this, when I press on L the layout doesn't move. I don't get why... Could you explain me what I am doing wrong please?
Button "L":
Button cmd_change = (Button) findViewById(R.id.cmd_changesite);
cmd_change.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Log.v("TEST: ", ""+shellpreference.getInt("CHANGESITE", 0));
if(sharedpreference.getInt("CHANGESITE", 0) == 0){
RelativeLayout relativeLayout= (RelativeLayout)findViewById(R.id.rl_changesite);
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
relativeLayout.setLayoutParams(params);
sharedpreference.setInt("CHANGESITE", 1);
}else{
RelativeLayout relativeLayout= (RelativeLayout)findViewById(R.id.rl_changesite);
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
relativeLayout.setLayoutParams(params);
sharedpreference.setInt("CHANGESITE", 0);
}
}
});

The problem is with the parent layout. It is set to wrap_content.
Change the width of the parent RelativeLayout to match_parent and most likely the problem should be fixed.
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_below="@+id/RelativeLayout01" >

Along with the above the problem is that, when the preference changes between 0 to 1 and back to 0 you never remove the previously assigned rule. (You only call params.addRule(..) ). This is the problem as now it has both ALIGN_PARENT_RIGHT and ALIGN_PARENT_LEFT.
To resolve this, you could use the removeRule() method:
if(sharedpreference.getInt("CHANGESITE", 0) == 0){
RelativeLayout relativeLayout= (RelativeLayout)findViewById(R.id.rl_changesite);
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
params.removeRule(RelativeLayout.ALIGN_PARENT_RIGHT);
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
relativeLayout.setLayoutParams(params);
sharedpreference.setInt("CHANGESITE", 1);
}
else {
RelativeLayout relativeLayout= (RelativeLayout)findViewById(R.id.rl_changesite);
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)relativeLayout.getLayoutParams();
params.removeRule(RelativeLayout.ALIGN_PARENT_LEFT);
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
relativeLayout.setLayoutParams(params);
sharedpreference.setInt("CHANGESITE", 0);
}
This method is only supported from API LEVEL 17 (JELLY_BEAN_MR1).
For lower version, simply create a new layout param and assign it to the RelativeLayout as follows:
if(sharedpreference.getInt("CHANGESITE", 0) == 0){
RelativeLayout relativeLayout= (RelativeLayout)findViewById(R.id.rl_changesite);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT); // add other rules from XML also
relativeLayout.setLayoutParams(params);
sharedpreference.setInt("CHANGESITE", 1);
}
else {
RelativeLayout relativeLayout= (RelativeLayout)findViewById(R.id.rl_changesite);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT); // add other rules from XML also
relativeLayout.setLayoutParams(params);
sharedpreference.setInt("CHANGESITE", 0);
}
Note: for method 2, you will have to add other rules from your XML file programmatically as you create a new instance of layout params each time so those defined in XML are not applied anymore.
