Led控制从内核到app的实现之app层（五）

1.新建两个button和一个testview,监听button，按下button1时,testview显示"LED setOn"，并点亮LED,按下button2时testview显示"LED setOff"，并关闭LED.

    private Button button1;
    private Button button2;
    private TextView textView2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        button1 = (Button) findViewById(R.id.button1);
        button2 = (Button) findViewById(R.id.button2);
        textView2 = (TextView) findViewById(R.id.textView2);
        button1.setOnClickListener(new Button.OnClickListener() {
            public void onClick(View v) {
                Log.v("asd", "button1");
                String str = "LED setOn";
                textView2.setText(str);
                ledHalService.setOn(0);

            }
        });
        button2.setOnClickListener(new Button.OnClickListener() {
            public void onClick(View v) {
                String str = "LED setOff";
                textView2.setText(str);
                ledHalService.setOff(1);
            }
        });
    }
