Android手機震動抖動效果的實現

(1)佈局檔案如下

<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;
    /**
     * 手機振動器
     */
    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);

        // 震動效果的系統服務
        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, "內容為空", 0).show();
                    Animation shake = AnimationUtils.loadAnimation(
                            MainActivity.this, R.anim.shake);
                    et_text.startAnimation(shake);

                    /*
                     * 震動的方式
                     */
                    // vibrator.vibrate(2000);//振動兩秒

                    // 下邊是可以使震動有規律的震動   -1:表示不重複 0:迴圈的震動
                    long[] pattern = { 200, 2000, 2000, 200, 200, 200 };
                    vibrator.vibrate(pattern, -1);
                }
            }
        });
    }
}

(3)使用到的兩個動畫檔案如下:
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)需要使用的許可權:

 <uses-permission android:name="android.permission.VIBRATE" />

這個效果一般只有在真機上誰可以做到,不在上圖展示。
