This document provides code snippets for various Android tasks. It shows how to load a custom font, create an alert dialog with positive and negative buttons, use layout weights of 0dp for height and weight, initialize and check the state of radio buttons, and more.

1. 1.Asset>>Font>>my custom font.ttf
TextView tv;
Typeface tv = Typeface.createFromAsset(getAssets(),"font/my custom font.ttf");
2. Creating a dialogue box --
public void DeleteSite(View v) {
AlertDialog.Builder builder = new
AlertDialog.Builder(MainActivity.this);
builder.setTitle("Deleting File..");
builder.setMessage("Are your sure?");
builder.setIcon(R.drawable.mylogo);
builder.setCancelable(false);
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int pos) {
Toast.makeText(getApplicationContext(), "This bullshit file is
deleted!",
Toast.LENGTH_LONG).show();
}
});
builder.setNegativeButton("Cancel", new
DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int pos) {
Toast.makeText(getApplicationContext(), "Dialogue Cancelled!",
Toast.LENGTH_LONG).show();
}
});
AlertDialog simpleDialog = builder.create();
simpleDialog.show();
}
}
3. Use 0dp height/weight while using layout weight.
4. RadioButton:
put the buttons in a radiogroup.
Java:
initialize: RadioButton radiobutton = (RadioButton)
findViewById(R.id.radiobutton);
Checked or Not : radiobutton.ischecked(); -- returns Bool;
5.
