Switch和 ToggleButton的用法

2、實現如下代碼

public class MainActivity extends AppCompatActivity {
    TextView tx1, tx2;
    Switch sw;
    ToggleButton tb;
    int a, b;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tx1 = (TextView) findViewById(R.id.textView);
        tx2 = (TextView) findViewById(R.id.textView2);
        sw = (Switch) findViewById(R.id.switch1);
        tb = (ToggleButton) findViewById(R.id.toggleButton);

        sw.setText("芝麻門");
        sw.setTextColor(Color.RED);
        sw.setOnClickListener(linstener1);
        tb.setText("開關2");
        tb.setTextColor(Color.GREEN);
        tb.setOnClickListener(linstener2);
        a = 1;
        b = 1;

    }

    //監聽器1要做的事情

    Switch.OnClickListener linstener1 = new Switch.OnClickListener() {
        public void onClick(View v) {
            if (a == 1) {
                tx1.setText("芝麻開門");
                tx1.setTextColor(Color.GREEN);
                a++;
            }
            else
            {tx1.setText("門已關");
                tx1.setTextColor(Color.BLACK);
                a=1;
            }
        }
    };
    //監聽器2要做的事情
    ToggleButton.OnClickListener linstener2 = new ToggleButton.OnClickListener() {
        public void onClick(View v) {
            if(b==1)
            {
                tx2.setText("燈已開");
                tx2.setTextColor(Color.RED);
                b++;
            }
            else
            {
                tx2.setText("燈已關");
                tx2.setTextColor(Color.BLACK);
                b=1;
            }
        }
    };
}

運行效果
