如何获取线性布局以填充Android中的父页面

Question

I have created a pagecontroller application and added it on my page in its own linear layout. However, I can not get the layout width to fill the entire parent page.. This is my code:

pagecontrol = new LinearLayout(this.context);
pagecontrol.setOrientation(LinearLayout.HORIZONTAL);
pagecontrol.setGravity(Gravity.CENTER_HORIZONTAL);

params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.FILL_PARENT);
pagecontrol.addView(btn,params);

public LinearLayout getView() {
        return pagecontrol;
    }

I have attached the screenshot of the page. Could anyone please advise?

Thanks in advance.

Answer 1

params = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
            LayoutParams.FILL_PARENT);

Answer 2

You must use these properties.

android:layout_width="fill_parent"
android:layout_height="fill_parent"

Answer 3

params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.FILL_PARENT); 

replace WRAP_CONTENT with FILL_PARENT it will work

Answer 4

Please check the height and width of layout if you take the outer layout of your linear layout.

Change it:

android:layout_width="fill_parent"
android:layout_height="fill_parent"
