手机震动可以是一种提醒或是替换铃声的事件,如果想要让手机乖乖的震动,需要创建Vibrator对象通过Vibrator方法来实现达到震动的模式,在Vibrator的构造方法中有四个参数前三个值是设置震动的大小,可以把数值改成一大一小这样就可以明显感觉到震动的差异,而最后一个值是震动的时间, Repeat=0时,震动会一直持续repeat=-1震动只会出现一轮,运动完毕后就不再震动
判断ToggleButton是否被开启。如果单击就是“ON”就会启动震动模式如果点击OFF就会关闭振动模式
先定义一个Activity
package cn.hwttnet.com.ui; import android.app.Activity; import android.app.Service; import android.os.Bundle; import android.os.Vibrator; import android.view.View; import android.view.View.OnClickListener; import android.widget.Toast; import android.widget.ToggleButton; public class EX05_06Activity extends Activity { private Vibrator vbt; private ToggleButton tb1, tb2, tb3; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); vbt = (Vibrator) getApplication().getSystemService( Service.VIBRATOR_SERVICE); final ToggleButton tb1 = (ToggleButton) findViewById(R.id.toggleButton1); final ToggleButton tb2 = (ToggleButton) findViewById(R.id.toggleButton2); final ToggleButton tb3 = (ToggleButton) findViewById(R.id.toggleButton3); //短震动 tb1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub if (tb1.isChecked()) { vbt.vibrate(new long[] { 100, 10, 100, 1000 }, -1); Toast.makeText(getApplicationContext(), "震动开启", Toast.LENGTH_LONG).show(); } else { vbt.cancel(); Toast.makeText(getApplicationContext(), "震动取消", Toast.LENGTH_LONG).show(); } } }); //长震动 tb2.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub if (tb2.isChecked()) { vbt.vibrate(new long[] { 100, 100, 100, 1000 }, 0); Toast.makeText(getApplicationContext(), "震动开启", Toast.LENGTH_LONG).show(); } else { vbt.cancel(); Toast.makeText(getApplicationContext(), "震动取消", Toast.LENGTH_LONG).show(); } } }); //节奏震动 tb3.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub if (tb3.isChecked()) { vbt.vibrate(new long[] { 1000, 50, 1000, 50,1000 }, 0); Toast.makeText(getApplicationContext(), "震动开启", Toast.LENGTH_LONG).show(); } else { vbt.cancel(); Toast.makeText(getApplicationContext(), "震动取消", Toast.LENGTH_LONG).show(); } } }); } }
定义一个main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TableLayout android:id="@+id/tableLayout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:collapseColumns="3" android:stretchColumns="1" > <TableRow android:id="@+id/tablerow1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center" > <ToggleButton android:id="@+id/toggleButton1" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="短震动" /> </TableRow> <TableRow android:id="@+id/tablerow2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center" > <ToggleButton android:id="@+id/toggleButton2" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="长震动" /> </TableRow> <TableRow android:id="@+id/tablerow3" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center" > <ToggleButton android:id="@+id/toggleButton3" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/textView3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="节奏震动" /> </TableRow> </TableLayout> </LinearLayout>
然后震动事件必须允许android .permission.VIBARTE权限
<uses-permission android:name="android.permission.VIBRATE"/>
试着把震动的大小做多变化的改变在long[]里面多做一些变化
tb3.vibrate(new long[]{10000,500,10000,500,10000,500,10000},0);
