实现震动功能代码:
//要注意再mainfest中添加权限:< uses-permission android:name="android.permission.VIBRATE"/>

public class MainActivity extends AppCompatActivity {
//创建震动服务对象
private Vibrator mVibrator;
private ToggleButton toggleButton1,toggleButton2,toggleButton3;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
//获取手机震动服务
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) {
//判断是否开启
if(toggleButton1.isChecked()){
//设置震动周期,数组表示时间:等待+执行,单位是毫秒,下面操作代表:等待100,执行100,等待100,执行1000,
//后面的数字如果为-1代表不重复,之执行一次,其他代表会重复,0代表从数组的第0个位置开始
mVibrator.vibrate(new long[]{100,100,100,1000},-1);
Toast.makeText(MainActivity.this,getString(R.string.str_ok),Toast.LENGTH_SHORT).show();
}else{
//取消震动
mVibrator.cancel();
Toast.makeText(MainActivity.this,getString(R.string.str_end),Toast.LENGTH_SHORT).show();
}
}
}
private class myOnClickListener2 implements View.OnClickListener{
@Override
public void onClick(View v) {
if(toggleButton2.isChecked()){
mVibrator.vibrate(new long[]{100,10,100,1000},0);
Toast.makeText(MainActivity.this,getString(R.string.str_ok),Toast.LENGTH_SHORT).show();
}else{
mVibrator.cancel();
Toast.makeText(MainActivity.this,getString(R.string.str_end),Toast.LENGTH_SHORT).show();
}
}
}
private class myOnClickListener3 implements View.OnClickListener{
@Override
public void onClick(View v) {
if(toggleButton3.isChecked()){
mVibrator.vibrate(new long[]{1000,50,1000,50,1000},0);
Toast.makeText(MainActivity.this,getString(R.string.str_ok),Toast.LENGTH_SHORT).show();
