Android getString(R.string.text) in a static method

Posted on by

Sometimes there is a need to access recourses from static methods.
In order to do this we need to pass along the Context to the method and use getString from that Context.

Example:

package com.f15ijp.android.test;
 
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.view.WindowManager;
 
public class Help {
	public static AlertDialog helpDialog(Context theContext, String helpMessage){
	AlertDialog alertDialog = new AlertDialog.Builder(theContext).create();            	
    	alertDialog.setTitle("Help");
    	alertDialog.setMessage(helpMessage);
    	alertDialog.setButton(theContext.getString(R.string.close_help_btn), new DialogInterface.OnClickListener() {
	    @Override
	    public void onClick(DialogInterface dialog, int which) {
		return;						
	    }
	});
    	WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
        lp.copyFrom(alertDialog.getWindow().getAttributes());
        lp.width = WindowManager.LayoutParams.FILL_PARENT;
        lp.height = WindowManager.LayoutParams.FILL_PARENT;
        /*by calling alertDialog.show() now and then again after setAttributes the background
         * the background activity is replaced by a black box. 
         * If this first alertDialog.show() is removed then the (current) acitivity is used as a background. 
         */
        alertDialog.show();
        alertDialog.getWindow().setAttributes(lp);
        return alertDialog;
    }
}
