What should I use in place of getWidth() and getHeight() to know when width is greater and when height is greater [duplicate]

Question

import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Display;
import android.view.WindowManager;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        FragmentManager fm=getFragmentManager();
        FragmentTransaction ft= fm.beginTransaction();


        WindowManager wm= getWindowManager();
        Display d=wm.getDefaultDisplay();

        if (d.getWidth()>d.getHeight())
        {
            Fragment1 f1 = new Fragment1();
            ft.replace(android.R.id.content, f1);
        }
        else
        {
            Fragment2 f2 = new Fragment2();
            ft.replace(android.R.id.content, f2);
        }
    ft.commit();
    }
}

I am trying to use fragments in android and want to display fragment1 when width of display is greater than height of display and fragment2 when height of display is greater than width of display but when using getWidth() and getHeight() android studio is saying that these methods are depricated. Then how to know when width is greater and when height is greater?

Answer 1

Use DisplayMetrics instead of Display.

Try this:

import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Display;
import android.view.WindowManager;
import android.util.DisplayMetrics;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        FragmentManager fm=getFragmentManager();
        FragmentTransaction ft= fm.beginTransaction();

        DisplayMetrics displayMetrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
        int height = displayMetrics.heightPixels;
        int width = displayMetrics.widthPixels;

        if (width > height)
        {
            Fragment1 f1 = new Fragment1();
            ft.replace(android.R.id.content, f1);
        }
        else
        {
            Fragment2 f2 = new Fragment2();
            ft.replace(android.R.id.content, f2);
        }

        ft.commit();
    }
}

You can use DisplayMetrics

DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int Width = displaymetrics.widthPixels;

if (Width  > height )
    {
        Fragment1 f1 = new Fragment1();
        ft.replace(android.R.id.content, f1);
    }
    else
    {
        Fragment2 f2 = new Fragment2();
        ft.replace(android.R.id.content, f2);
    }

Answer 3

DisplayMetrics displaymetrics = new DisplayMetrics();
mContext.getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int screenWidth = displaymetrics.widthPixels;
int screenHeight = displaymetrics.heightPixels;

Answer 4

Try

 context.getWindowManager().getDefaultDisplay().getMetrics(dm);
 if(dm.widthPixels > dm.heightPixels) {
     //width is greater, i.e. landscape
     Fragment1 f1 = new Fragment1();
        ft.replace(android.R.id.content, f1);
 } else {
     //height is greater i.e. portrait
     Fragment2 f2 = new Fragment2();
     ft.replace(android.R.id.content, f2);
 }

You can detect orientation directly by overriding onConfigurationChanges in MainActivity

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        Fragment1 f1 = new Fragment1();
        ft.replace(android.R.id.content, f1);
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        Fragment2 f2 = new Fragment2();
        ft.replace(android.R.id.content, f2);
    }
}

//Add configChanges in manifest
<activity android:name=".MainActivity"
      android:configChanges="orientation|keyboardHidden"
      android:label="@string/app_name">

Use this to get width and height.

int Measuredwidth = 0;  
int Measuredheight = 0;  
Point size = new Point();
WindowManager wm = getWindowManager();

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)    {
    wm.getDefaultDisplay().getSize(size);
    Measuredwidth = size.x;
    Measuredheight = size.y; 
}else{
    Display d = w.getDefaultDisplay(); 
    Measuredwidth = d.getWidth(); 
    Measuredheight = d.getHeight(); 
}
