Fix Screen orientation

问题

I wanted to fix screen orientation as a landscape mode in tab i.e on 7" I am calculating the inch of the device in my coding and is setting it as:

int inch=((int)height_pixel1/(int)xdpi);
if(inch>=6){
    orientation=true;
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
} else {
    orientation=false;
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

and the problem is firstly it displays me the screen orientation as according to my requirement,but when processing is going on in between , then it changes the orientation as portrait way and again in landscape way.. It is still toggle between these two orientation and I want to make a fixed orienattion for my whole application...Is there any property that I am missing here??

Create a folder layout-xlarge-land and put your XML in it... it should be designed for landsacpe screen.. also You have to give

android:largeScreens="true"  in manifest... 


res/layout/my_layout.xml             // layout for normal screen size ("default")
res/layout-small/my_layout.xml       // layout for small screen size
res/layout-large/my_layout.xml       // layout for large screen size
res/layout-xlarge/my_layout.xml      // layout for extra large screen size
res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation





 <supports-screens android:resizeable=["true"| "false"]
                      android:smallScreens=["true" | "false"]
                      android:normalScreens=["true" | "false"]
                      android:largeScreens=["true" | "false"]
                      android:xlargeScreens=["true" | "false"]
                      android:anyDensity=["true" | "false"]
                      android:requiresSmallestWidthDp="integer"
                      android:compatibleWidthLimitDp="integer"
                      android:largestWidthLimitDp="integer"/>

Try it out, just set it inside the AndroidManifest.xml file:

<activity android:name=".ActivityName"
              android:label="@string/app_name"
              android:configChanges="orientation|keyboardHidden">  
              // Prevent application restart on orientation change
