If our Android app wants to invoke the system's vibration service when the button is pressed, we have to androidmainfest.xml it with the appropriate permissions.
<uses-permission android:name= "Android.permission.VIBRATE"/>
Then it's
Vibrator Vibrator = (Vibrator) getsystemservice (Vibrator_service);
Vibrator.vibrate (3000);
Set the vibration period of the vibrate
Vibrator.vibrate (New long[]{1000,2000,3000,4000}, 0);
Here again on the Internet to find a good way to write the vibration of the class
package com.lxb.switchdemo; import android.app.activity; Import android.app.Service; import android.os.vibrator; import
android.widget.linearlayout; /** * mobile phone vibration tools * * @author Administrator * */ public class vibratorutil { /** * &NBSP;FINAL&NBSP;ACTIVITY&NBSP;ACTIVITY&NBSP: The activity instance of the method is invoked long milliseconds : the length of the vibration, in milliseconds. &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;*&NBSP;LONG[]&NBSP;PATTERN&NBSP: Custom Vibration mode . The meaning of the numbers in the array is [static length, length of vibration, length of stillness, length of vibration ...] The length of the unit is milliseconds * boolean isRepeat : whether repeated vibrations, if true, repeated vibrations, If it is false, only once */ public static voiD vibrate (final activity activity, long milliseconds) { Vibrator vib = (vibrator) activity .getsystemservice ( Service.vibrator_service); vib.vibrate (milliseconds ); } public static void vibrate (final activity activity, long[] pattern, boolean isrepeat) {
Vibrator vib = (Vibrator) activity . Getsystemservice (Service.vibratOr_service); vib.vibrate (pattern, isRepeat ? 1 : -1); } }
Of course, when called in your activity, you only need to add the
Vibratorutil.vibrate (switch_demoactivity.this) to the onclick;
Simple vibration mechanism can be implemented
down to summarize the mechanism implementation of the key sound,
public class mainactivity extends activity { private Button mButton01; private soundpool sp;//declares a soundpool private int music;//defines an integral type with load () ; To set suondid @Override public void oncreate (bundle savedinstancestate) {
super.oncreate (savedinstancestate);
setcontentview (R.layout.activity_main); mbutton01= (Button) Findviewbyid (R.id.mbutton01); sp= new soundpool (10, AudioManager.STREAM _SYSTEM,&NBSP;5);//The first parameter is the sameThe maximum number of data streams to play, the second data stream type, and the third for sound quality music = sp.load (this, r.raw.start, 1); //put your voice footage into Res/raw, the 2nd parameter is the resource file, and the 3rd is the priority of the music mbutton01.setonclicklistener (new Onclicklistener () { @ override public void onclick (view v) { sp.play (music, 1, 1, 0, 0, 1); } } } }
Raw is a new folder under Res, which is a direct resource file that does not need to be compiled, and, of course, to avoid the need to recognize the key voice in some machines, it is best to convert the audio format that needs to be loaded into the Ogg format.
