< 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 > |

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
1
2
3
|
<? xml version = "1.0" encoding = "utf-8" ?> < cycleInterpolator xmlns:android = "http://schemas.android.com/apk/res/android" android:cycles = "7" /> |
shake.xml
1
2
3
4
5
6
|
<? 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:
1
|
<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。
