    super.onCreate(savedInstanceState);
    setContentView(R.layout.my_task);


    this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);


    cus_name_txt = (TextView)findViewById(R.id.cus_name_txta);

           contact_no_txt = (TextView)findViewById(R.id.contact_no_txta);

    task_detail_txt = (TextView)findViewById(R.id.task_detail_txt);

This depends on whether you want your database to be local or stored on a remote server.

If it is local, You'll have to convert your MYSQL db to a SQLite db since this the one that Android supports.

See here for instructions:

Convert MySQL to SQlite

Then you can access it using the native android methods. See db tutorial here:

http://www.vogella.com/articles/AndroidSQLite/article.html

If it is hosted on a remote server, then you'll have to create REST API's (by writing server side code using a language like PHP, Ruby, Python etc) that your Android app can consume to obtain the data from the db.

There are other options that avoid REST API's as well. See:

How to get from a MySql server to an Android app?

See here for a beginners tutorial on REST:
