Here date is typically stored in yyyy-mm-dd hh:ii:ss format. Ex. 2021-01-26 12:22:31 The logical flow is important to understantd. 1. MySQL returns a string as date. 2. We convert this strDate to Date Format. 3. Now we change the date format to desired formatting. 4. Next we convert the date to string again. 5. Finally we return the newly formatted date string. The code blocks:- String dateCreated = "2021-01-26 12:22:05"; String formattedDate = null ; try { formattedDate = getFormattedDate (dateCreated); } catch (ParseException e) { e.printStackTrace(); } Toast.makeText(this, formattedDate,LENGTH_SHORT).show(); /* Now create a function */    public static String getFormattedDate(String strDate) throws ParseException { Date date = new SimpleDateFormat( "yyyy-MM-dd ...

First add dependencies to android file   Add recyclerview library in build.gradle file implementation 'androidx.recyclerview:recyclerview:1.1.0' Step 2 activity_complaints.xml This XML file holds recyclerview component <? xml version ="1.0" encoding ="utf-8" ?> < androidx.recyclerview.widget.RecyclerView xmlns: android ="http://schemas.android.com/apk/res/android" android :layout_height ="match_parent" android :layout_width ="match_parent" android :id ="@+id/rvComplaintsList" > </ androidx.recyclerview.widget.RecyclerView > Step 3 This will contain Components to be repeated via RecyclerView. complainsts_list_layout.java <? xml version ="1.0" encoding ="utf-8" ?> < LinearLayout xmlns: android ="http://schemas.android.com/apk/res/android" android :orientation ="horizontal" android :layout_width ="match_parent" and...

This is h ow you can Align Views at The Bottom of The Screen You know, you have to go to layout_main.xml file (If this is the layout you want to tweak with). Here we add a LinearLayout Component. Then place a TextView Component within that liner layout. Most important note: Add android:gravity="bottom" in the LinearLayout Component Add  android :gravity ="center_horizontal" in the TextView Component You are done! Here goes your SAMPLE code. < LinearLayout android :layout_width ="match_parent" android :layout_height ="match_parent" android :gravity ="bottom" android :orientation ="horizontal" > < TextView android :id ="@+id/bottomText" android :layout_width ="match_parent" android :padding ="2dp" android :textSize ="18sp" android :layout_height ="wrap_content" android :background ="@color/cardview_...

 Sharing data between activities in Android is as simple as this. Put Data Intent intent = new Intent(MainActivity. this , BrowseActivity. class ); intent.putExtra( "targetUrl" , "https://www.google.com" ); startActivity(intent); Get Data Intent intent = getIntent(); String targetUrl = intent.getStringExtra( "targetUrl" ); Here we put data in one activity. And retrieve the data in another activity. So, we need to .java files. Say, you have FirstActivity.java and SecondActivity.java file. You put values in FirstActivity.java file. So, code to put data should go in this file: Intent intent = new Intent(MainActivity. this , BrowseActivity. class ); intent.putExtra( "targetUrl" , "https://www.google.com" ); startActivity(intent); Now you retrieve the values in SecondActivity.java file. To retrieve information, use Intent intent = getIntent(); String targetUrl = intent.getStringExtra( "targetUrl" ); This is really simple. Obviously...
