title: Android popup window not filling screen size?
body: <p>I am trying to make a simple pop up window. But every time I make one, it ends up being super small...and not the length I want it to be. This is how the pop up looks:

  <p>Here is my layout for the pop up:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/popup_element"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:background="#444444"
      android:padding="10px"
      android:orientation="vertical"&gt;
  
      &lt;TextView
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:layout_centerHorizontal="true"
          android:text="Transfering data"
          android:textColor="@color/white"/&gt;
  
      &lt;TextView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_gravity="center_vertical"
          android:text="Status"
          android:textColor="@color/white"/&gt;
  
      &lt;TextView android:id="@+id/server_status_text"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="Awaiting answer..."
          android:paddingLeft="10sp"
          android:textColor="@color/white"/&gt;
  
      &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:orientation="horizontal"
          android:gravity="center_horizontal|bottom"&gt;
  
          &lt;Button android:id="@+id/end_data_send_button"
              android:layout_width="100dp"
              android:layout_height="100dp"
              android:drawablePadding="3sp"
              android:layout_centerHorizontal="true"
              android:text="Cancel" /&gt;
      &lt;/LinearLayout&gt;
  &lt;/LinearLayout&gt;

  <p>Here is my java code:</p>
  
  <pre><code>private PopupWindow pw;
          private void bindActivity() {
  
              fabButton = (ImageButton) findViewById(R.id.activity_profileView_FAB);
              fabButton.setOnClickListener(new View.OnClickListener() {
                  @Override
                  public void onClick(View v) {
                      initiatePopupWindow();
                  }
              });
  
  
          }
       private void initiatePopupWindow() {
              try {
                  //We need to get the instance of the LayoutInflater, use the context of this activity
                  LayoutInflater inflater = (LayoutInflater) ProfileView.this
                          .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                  //Inflate the view from a predefined XML layout
                  View layout = inflater.inflate(R.layout.popup,
                          (ViewGroup) findViewById(R.id.popup_element));
                  // create a 300px width and 470px height PopupWindow
                  pw = new PopupWindow(layout, 300, 470, true);
                  // display the popup in the center
                  pw.showAtLocation(layout, Gravity.CENTER, 0, 0);
  
                  TextView mResultText = (TextView) layout.findViewById(R.id.server_status_text);
                  Button cancelButton = (Button) layout.findViewById(R.id.end_data_send_button);
                  cancelButton.setOnClickListener(cancel_button_click_listener);
  
              } catch (Exception e) {
                  e.printStackTrace();
              }
          }
  
          private View.OnClickListener cancel_button_click_listener = new View.OnClickListener() {
              public void onClick(View v) {
                  pw.dismiss();
              }
          };
  </code></pre>
