How to set list view height programatically in android

Question

I am making an application in which my keyboard comes up on the activity and it hides may header view (layout) I have searched and tried adjust pane state hidden,adjust nothing all the attributes in manifest but nothing solved my problem then I found one the posts over stackover flow that you can calculate the spacing then set the height I implemented but the behaviour is still same this is the sanpshot when activity comes

but when keyborad pops up it hides my header view this is snapshot of what's happening

this is my manifest code

 <activity
        android:name="com.dd.sproutchat.ChatActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="adjustNothing">
    </activity>

this is my layout of that activity

and this is my activity code for calculating height of listview

private static boolean keyboardHidden = true;
    private static int reduceHeight =0;

    final View decorView = this.getWindow().getDecorView();
    decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            Rect rect = new Rect();
            decorView.getWindowVisibleDisplayFrame(rect);
            int displayHeight = rect.bottom - rect.top;
            int height = decorView.getHeight();
            boolean keyboardHiddenTemp = (double) displayHeight / height > 0.8;
            int mylistviewHeight = Lv_Chat.getMeasuredHeight();
            if (keyboardHiddenTemp != keyboardHidden) {
                keyboardHidden = keyboardHiddenTemp;
                if (!keyboardHidden) {
                    reduceHeight = height - displayHeight;
                    RelativeLayout.LayoutParams mParam = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, mylistviewHeight - reduceHeight);
                    Lv_Chat.setLayoutParams(mParam);
                    Lv_Chat.requestLayout();
                } else {
                    RelativeLayout.LayoutParams mParam = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, mylistviewHeight + reduceHeight);
                    Lv_Chat.setLayoutParams(mParam);
                    Lv_Chat.requestLayout();
                }
            }
        }
    });

I have also tried this link for setting xml file http://codetheory.in/android-add-views-view-groups-listview-gridview/

any help please

Answer 1

I think you should use adjustResize instead of adjustNothing and add android:fitsSystemWindows="true" in your root RelativeLayout instead of programmatically trying to resize your views.

Answer 2

To change the height of ListView you should use LayoutParams:

ViewGroup.LayoutParams param = listView.getLayoutParams();
param.height = anynumberhere;
listView.setLayoutParams(param);
listView.requestLayout();

According to your question, this is the way to change the ListView's height, but i don't think its the rite approach to make that header of yours stay in its place.
