I want to get the exact height of the visible layout programmatically as I shown in figure. I used Sherlock fragment activity as main activity which contain different fragments. I tried to get the height and width of the screen through Display and display matrix, but it give whole screen height and width.but i want to get only visible view of the child activity. please help me. thanks in advance.
Main XML (of Tabbar)
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TabHost
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="@dimen/fr_layout_width"
android:layout_height="@dimen/fr_layout_height"
android:layout_weight="0" />
<FrameLayout
android:id="@+android:id/realtabcontent"
android:layout_width="fill_parent"
android:layout_height="@dimen/fr_layout_height"
android:layout_weight="1" />
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="@dimen/hdpi_tab_layout_height"
android:layout_weight="0"
android:background="@android:color/transparent"
android:gravity="bottom"
android:orientation="horizontal" />
</LinearLayout>
</TabHost>
</android.support.v4.widget.DrawerLayout>
child xml (Xml of child Activity)
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/mainscroll"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context=".MainActivity">
<LinearLayout
android:id="@+id/topliner"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
</LinearLayout>
</ScrollView>
It will get height of the whole window
Display display = getWindowManager().getDefaultDisplay();
Displayheight = display.getHeight();
Now take take height of ActionBar
ActionBar actionBar = getActionBar();
actionBarHeight = actionBar.getHeight();
let's take one tabHost & it's height for ex.
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
Intent intent;
intent = new Intent().setClass(this, vTab1.class);
spec = tabHost.newTabSpec("First").setIndicator("First").setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, vTab2.class);
spec = tabHost.newTabSpec("Second").setIndicator("Second").setContent(intent);tabHost.addTab(spec);
int height = tabHost.getTabWidget().getHeight();
Now subtract Height of actionbar & tabWidget from Window Height
DesiredArea = DisplayHeight - (actionBarHeight + height);
this might be the solution or you can use similar type of logic.. i'm not telling this vl definately work.
Sorry for Disturb , I solved my question for getting some ideas through other answer but i see some deprecated method which is suggested to solve it.
for actionbar And tabbar height
int tabHeight = mTabHost.getTabWidget().getHeight();
int actionbarheight = getSupportActionBar().getHeight();//getActionbar() insted of for Api greater 13 than
height of statusbar
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
int statusbarheight = getStatusBarHeight();
for getting screen size
Display display = getWindowManager().getDefaultDisplay();
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.HONEYCOMB_MR2)
{
width = display.getWidth(); // deprecated
height = display.getHeight()- (tabHeight + actionbarheight + statusbarheight );
}
else {
Point size1 = new Point();
display.getSize(size1);
width = size1.x;
height = size1.y - (tabHeight + actionbarheight + statusbarheight);//visible layout height
}
int height = getWindow().getWindowManager().getDefaultDisplay().getHeight();
