public class TestMain extends ActionBarActivity {
    private  Button mButton01;
    private  TextView mTextView01;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test_main);

        mButton01 = (Button) findViewById(R.id.button01);
        mTextView01 = (TextView) findViewById(R.id.textView01);

        mButton01.setOnClickListener(new Button.OnClickListener() //button点击后 触发事件
        {    @Override
             public  void onClick(View v)
                 {mTextView01.setText("hi,this is test");}        //事件触发 textView01字符串改变
        });
    }

public void jumpToLayout01
{
setContentView(R.layout.mylayout);} //调用mylayout.xml界面
