Show text for 3/4 second then another text will show there in one activity
call this inside onCreate function. we are using coroutine here. follow this link for more reference -> https://stackoverflow.com/a/62065829/8879652
lifecycleScope.launch {
myText.text = "text 1"
delay(3000L)
myText.text = "text 2"
delay(4000L)
myText.text = "text 3"
}
I want to make a button which will post a message once the button is hit. Here is my main activity.java :

Hope you undestand my question, and here is my video reference from youtube :

Replace the onCreate() method as
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListnerOnButton(); //Add this line to your code.
}
you are doing wrong in android you can set click listener by two ways
1. In Java code
2. In XML
in your example you are doing runtime in java code so it will not show in XML editor
in your case just call your addListenerOnButton in onCreate it will work
if you want it in xml
add onClick function in activity class as below
public void buttonClick(View v)
{
//do what you want
}
then this buttonClick will be shown in editor or you can directly add in xml button onClick attribute
<Button ...
android:onClick="buttonClick"/>
I want to show selected images from gallery with gridview.
But, all the tutorial is just get image from project file..
like this..
// Keep all Images in array
public Integer[] mThumbIds = {
R.drawable.pic_1, R.drawable.pic_2,
};
I coded like there is add button, if users click it,
user can save name and photo. And if they save it, shows the photo with gridview..
those data would save in sqlite db.
How can I show the image from sqlite?

If you change the layout background you will get what you want
You copy the below code and in button onclick call
Intent i=new Intent(MainActivity.this,SimpleCalendarViewActivity.class);
startActivity(i);
And in android Manifest File for SimpleCalendarViewActivity add this theme.. It will display this as a Dialog. check it out
android:theme="#android:style/Theme.Dialog"
