R.layout.... compilation errors

You are working in your android project. Everything was fine. Suddenly you start getting lot of errors. The errors are in all the lines which use R like R.layout, R.drawable etc.

Just check your import statements. Most probably there is an import which says

import android.R;

Hence all the resources are tried in android.R., Not in your R.java file. 

Remove the import statements. And all these compilations errors vanish

Simple ListView Adapter and list item select

When you are using a listview in your applications many a times you will write your own adapter to display item. But if your list is very simple showing a list of strings, you can use inbuilt adapters like ArrayAdapter, SimpleCursorAdapter etc.

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ListView android:layout_height="wrap_content" android:id="@+id/listView1" android:layout_width="match_parent" android:layout_margin="20dp"> </ListView> </LinearLayout>

DatePickers in Android

DatePicker is a view which lets the user select a date showing a calendar or 3 spinners for dd, mm and yy.

Let us see how to use this.
Easy Method: To use a DatePicker you can use DatePickerDialog. This can be created and shown programmatically too.

publicvoidonCreate(Bundle b){/*********/ Button btn =(Button)findViewById(R.id.btn); btn.setOnClickListener(new View.OnClickListener(){@OverridepublicvoidonClick(View v){ showPickerDialog();}});}privatevoidshowPickerDialog(){ DatePickerDialog dtPickerDlg =new DatePickerDialog(this,this, 2017,10,20); dtPickerDialog.show();}

In our xml file, let us have a button and in the onclick listener of the button, let us display the date picker dialog - we call showPickerDialog.

In showPickerDialog,  we are using a random date to initialize.

The first  parameter is the context. Second parameter is the class which implements the interface OnDateSetListener. Next three parameters are year, month (Jan is 0) and …
