Pragmatically set Button in Right Side in Android

Question

I was Creating Button Programatically using Linear Layout. But I Can't Change Logout Button Alignment to Right Side.

Thanks in Advance...

My Code is

lView = new LinearLayout(Main2Activity.this);
                   // lView.setPadding(0,150,0,0);
                    lView.setBackgroundColor(Color.parseColor("#EDFCFC"));
                    lView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));

                    Button logout = new Button(Main2Activity.this);
                    logout.setText("Logout");
                    logout.setGravity(Gravity.CENTER);

                    logout.setBackgroundColor(Color.parseColor("#F53F37"));
                    lView.addView(logout);

Answer 1

The setGravity that you are using is for the text inside the button . In order to set the gravity of the entire button you need to work with the layoutParams . Please try the below code:

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.CENTER; 
logout.setLayoutParams(params);

Answer 2

try this:

 RelativeLayout rl = new RelativeLayout(Main2Activity.this);
Button logout = new Button(Main2Activity.this);
logout.setText("Hello, World");

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams
        (LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
logout.setBackgroundColor(Color.parseColor("#F53F37"));
rl.addView(logout, lp);

Answer 3

you can try in your xml file to put in the Button the code :

android:layout_marginLeft="how much dp you want"

or try :

android:layout_gravity="right"
