Android实现手机震动效果
本文实例介绍了Android实现手机震动、抖动效果,分享给大家供大家参考,具体内容如下
(1)布局文件如下
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <EditText android:id="@+id/et_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_marginTop="16dp" android:ems="10" > <requestFocus /> </EditText> <Button android:id="@+id/btn_submit" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/et_text" android:layout_below="@+id/et_text" android:layout_marginTop="38dp" android:text="提交" /> </RelativeLayout>
(2)MainActivity.java
package com.example.test11; import android.app.Activity; import android.os.Bundle; import android.os.Vibrator; import android.text.TextUtils; import android.view.View; import android.view.View.OnClickListener; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import android.widget.Button; import android.widget.EditText; import android.widget.Toast; public class MainActivity extends Activity { private EditText et_text; private Button btn_submit; /** * 手机振动器 */ private Vibrator vibrator; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); et_text = (EditText) this.findViewById(R.id.et_text); btn_submit = (Button) this.findViewById(R.id.btn_submit); // 震动效果的系统服务 vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE); btn_submit.setOnClickListener(new OnClickListener() { String text = et_text.getText().toString().trim(); public void onClick(View v) { if (TextUtils.isEmpty(text)) { Toast.makeText(MainActivity.this, "内容为空", 0).show(); Animation shake = AnimationUtils.loadAnimation( MainActivity.this, R.anim.shake); et_text.startAnimation(shake); /* * 震动的方式 */ // vibrator.vibrate(2000);//振动两秒 // 下边是可以使震动有规律的震动 -1:表示不重复 0:循环的震动 long[] pattern = { 200, 2000, 2000, 200, 200, 200 }; vibrator.vibrate(pattern, -1); } } }); } }
(3)使用到的两个动画文件如下:
cycle_7.xml
<?xml version="1.0" encoding="utf-8"?> <cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" android:cycles="7" />
shake.xml
<?xml version="1.0" encoding="utf-8"?> <translate xmlns:android="http://schemas.android.com/apk/res/android" android:duration="1000" android:fromXDelta="0" android:interpolator="@anim/cycle_7" android:toXDelta="10" />
(4)需要使用的权限:
<uses-permission android:name="android.permission.VIBRATE" />
希望本文所述对大家学习Android软件编程有所帮助。
