Android學習筆記 - 震動(Vibrator)

1. 若要在應用程式內使用到震動這個服務，需先在AndroidManifest.xml允許存取android.permission.VIBRATE這個權限。


2. MainActivity.java

package org.me.android_vibrate;
import android.app.Activity;
import android.app.Service;
import android.os.Bundle;
import android.os.Vibrator;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);
        Spinner spinner = (Spinner) findViewById(R.id.spinnner);
        ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_spinner_item,new String[]{"長震動","短震動","連續短震動"});
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter);

        spinner.setOnItemSelectedListener(new Spinner.OnItemSelectedListener(){
            public void onItemSelected(AdapterView adapterView, View view, int position, long id){
                //取得震動服務
                Vibrator myVibrator = (Vibrator) getApplication().getSystemService(Service.VIBRATOR_SERVICE);
                switch(position) {
                    case 0:
                        //震動3秒
                        myVibrator.vibrate(3000);
                        break;
                    case 1:
                        //震動0.1秒
                        myVibrator.vibrate(100);
                        break;
                    case 2:
                        //停0.01秒之後震動0.1秒(重覆三次)
                        myVibrator.vibrate(new long[]{10, 100, 10, 100, 10, 100}, -1);
                        break;
                    default:
                        break;
                }
            }
            public void onNothingSelected(AdapterView arg0) {
                Toast.makeText(MainActivity.this, "您沒有選擇任何項目", Toast.LENGTH_LONG).show();
            }
        });
    }
}

3. main.xml(Layout)

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">" 
    <Spinner
        android:id="@+id/spinnner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
    </Spinner>
</LinearLayout>

4. AndroidManifest.xml

<?xml version="1.0" encoding="UTF-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
     package="org.me.android_vibrate">
    <application>
         <activity android:name=".MainActivity" android:label="Vibrate">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
    <uses-permission android:name="android.permission.VIBRATE" />
</manifest>
