废话少说，直奔主题~！

结构如图：

Tel_DaiActivity.java代码:

public class Tel_DaiActivity extends Activity {



	private EditText tel_num_txt;

	private Button submit_btn;

	private Button reset_btn;



	/** Called when the activity is first created. */

	@Override

	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);

		findAll();

		bind();

	}



	public void findAll() {

		tel_num_txt = (EditText) this.findViewById(R.id.tel_num_txt);

		submit_btn = (Button) this.findViewById(R.id.submit_btn);

		reset_btn = (Button) this.findViewById(R.id.reset_btn);

	}



	public void bind() {

		submit_btn.setOnClickListener(mylistener);

		reset_btn.setOnClickListener(mylistener);

	}



	private View.OnClickListener mylistener = new OnClickListener() {



		public void onClick(View v) {

			// TODO Auto-generated method stub

			switch (v.getId()) {

			case R.id.submit_btn:

				Intent it = new Intent(Intent.ACTION_CALL, Uri.parse("tel:"

						+ tel_num_txt.getText().toString().trim()));

                startActivity(it);

				break;

			case R.id.reset_btn:

				tel_num_txt.setText("");

				break;

			default:

				break;

			}

		}

	};

}

main.xml代码:
