super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.login);
signup_text = (TextView) findViewById(R.id.sign_up);
signup_text.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(login.this, register.class));
}
});
PHONE_NO = (EditText) findViewById(R.id.phone_no);
PASSWORD = (EditText) findViewById(R.id.password);
login_button = (Button) findViewById(R.id.login_button);
login_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String phone_no = PHONE_NO.getText().toString();
String password = PASSWORD.getText().toString();
if (phone_no.equals("") || password.equals("")) {
builder = new AlertDialog.Builder(login.this);
builder.setTitle("Something went wrong...");
builder.setMessage("Please fill all the fields...");
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
} else {
BackgroundTask backgroundTask = new BackgroundTask(login.this);
backgroundTask.execute("login", phone_no, password);
}
}
});
}
}
и это backgroundtask.java
