android 之實現手機震動功能

標籤：

介面：利用weight屬性，能比較好得移植到平板上。

實現震動功能代碼：
//要注意再mainfest中添加許可權：<uses-permission android:name="android.permission.VIBRATE"/>

public class MainActivity extends AppCompatActivity {
    //建立震動服務物件
    private Vibrator mVibrator;
    private ToggleButton toggleButton1,toggleButton2,toggleButton3;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        init();
        //擷取手機震動服務
        mVibrator=(Vibrator)getApplication().getSystemService(Service.VIBRATOR_SERVICE);
        toggleButton1.setOnClickListener(new myOnClickListener1());
        toggleButton2.setOnClickListener(new myOnClickListener2());
        toggleButton3.setOnClickListener(new myOnClickListener3());
    }
    private void init(){
        toggleButton1=(ToggleButton)findViewById(R.id.button1);
        toggleButton2=(ToggleButton)findViewById(R.id.button2);
        toggleButton3=(ToggleButton)findViewById(R.id.button3);
    }
    private class myOnClickListener1 implements View.OnClickListener{
        @Override
        public void onClick(View v) {
            //判斷是否開啟
            if(toggleButton1.isChecked()){
                //設定震動周期，數組表示時間：等待+執行，單位是毫秒，下面操作代表:等待100，執行100，等待100，執行1000，
                //後面的數字如果為-1代表不重複，之執行一次，其他代表會重複，0代表從數組的第0個位置開始
                mVibrator.vibrate(new long[]{100,100,100,1000},-1);
                Toast.makeText(MainActivity.this,getString(R.string.str_ok),Toast.LENGTH_SHORT).show();
            }else{
                //取消震動
                mVibrator.cancel();
                Toast.makeText(MainActivity.this,getString(R.string.str_end),Toast.LENGTH_SHORT).show();
