调用系统软件apk
本帖最后由 蓝天-彭 于 2015-2-10 14:20 编辑之前介绍过简单快速搭建Eclipse开发环境 Eclipse的使用
本人android小白,刚学android应用,编写了一个简单的调用Cubieboard android系统软件的apk,这里调用了音乐播放器、视频播放器及图片浏览器,对于以后开发复杂的apk打下基础。
先上图:
功能:
点击播放音乐会自动使用系统自带音乐播放器播放背景音乐
点击播放视频可以播放自定义视频
点击浏览图片可以浏览自定义图片
具体实现如下:
1、新建一个android工程
2、删除MainActivity.java原有内容,添加如下内容:
package com.example.example8;
import java.io.File;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v)
{
/*新建一个Intent对象*/
Intent intent = new Intent();
/*指定intent要启动的类*/
intent.setClass(MainActivity.this, Activity02.class);
/*启动一个新的Activity*/
startActivity(intent);
/*关闭当前的Activity*/
MainActivity.this.finish();
}
});
Button btnVideo = (Button) this.findViewById(R.id.button2);
/*添加事件响应*/
btnVideo.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW);
/*调用外部存储设备videos文件夹下的test.avi*/
Uri uri = Uri.fromFile(new File("/mnt/usbhost0/videos/test.avi"));
intent.setDataAndType (uri, "video/mp4");
startActivity(intent);
}
});
Button btnVideo1 = (Button) this.findViewById(R.id.button3);
btnVideo1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW);
/*调用外部存储设备picturn文件夹下的test.jpg*/
Uri uri = Uri.fromFile(new File("/mnt/usbhost0/picturn/test1.jpg"));
intent.setDataAndType (uri, "image/*");
startActivity(intent);
}
});
}
}
3、新建Activity02.java文件,添加如下源码:
package com.example.example8;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class Activity02 extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main2);
Button button_start = (Button)findViewById(R.id.start);
Button button_stop = (Button)findViewById(R.id.stop);
// button_start.setBackgroundColor(Color.BLUE);
// button_stop.setBackgroundColor(Color.RED);
button_start.setOnClickListener(start);
button_stop.setOnClickListener(stop);
}
private OnClickListener start = new OnClickListener()
{
public void onClick(View v)
{
/*开启Service*/
startService(new Intent("com.yarin.Android.MUSIC"));
}
};
//停止按钮
private OnClickListener stop = new OnClickListener()
{
public void onClick(View v)
{
//ֹͣ停止Service
stopService(new Intent("com.yarin.Android.MUSIC"));
}
};
4、在res下新建raw文件夹,向其中添加test.mp3文件,在将test.mp3文件拷贝到该目录下
5、新建MusicService.java,添加如下内容:
package com.example.example8;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
public class MusicService extends Service
{
private MediaPlayer player;
public IBinder onBind(Intent arg0)
{
return null;
}
public void onStart(Intent intent, int startId)
{
super.onStart(intent, startId);
player = MediaPlayer.create(this, R.raw.test);
player.start();
}
public void onDestroy()
{
super.onDestroy();
player.stop();
}
}
6、删除fragment_main.xml原有内容,添加如下内容:
<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="com.example.example8.MainActivity$PlaceholderFragment" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/textView1"
android:layout_centerHorizontal="true"
android:layout_marginTop="54dp"
android:text="播放音乐" />
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/button1"
android:layout_below="@+id/button1"
android:layout_marginTop="41dp"
android:text="播放视频" />
<Button
android:id="@+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/button2"
android:layout_below="@+id/button2"
android:layout_marginTop="46dp"
android:text="浏览图片" />
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:text="这是一个调用系统软件的apk" />
</RelativeLayout>
7、新建main2.xml,添加如下内容:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<Button
android:id="@+id/start"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="开始播放"/>
<Button
android:id="@+id/stop"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="停止播放"
/>
</LinearLayout>
8、AndroidManifest.xml文件中添加如下内容以声明Activity02:
<activity android:name="Activity02"></activity>
<activity android:name="MusicService"></activity>
9、strings.xml中添加:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">播放音乐</string>
<string name="app_name">调用系统软件</string>
</resources>
10、编译,在Cubieboard上运行结果:
点击播放音乐弹出子界面:
点击开始播放,将播放音乐,由于音乐文件比较小,这里直接集成到了apk里,另外视频文件和图片需自行添加,只要更改一下源码中的相应的资源路径即可。
返回上一界面点击播放视频,出现:
选择播放器后即可播放,浏览图片也一样
android 中intent是经常要用到的。不管是页面牵转,还是传递数据,或是调用外部程序,系统功能都要用到intent。在做了一些intent的例子之后,整理了一下intent,希望对大家有用。由于intent内容太多,不可能真的写全,难免会有遗落,以后我会随时更新。如果你们有疑问或新的intent内容,希望交流。
★intent大全:

fileName = folder + name;
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, fileName);
values.put("_data", fileName);
values.put(Images.Media.PICASA_ID, fileName);
values.put(Images.Media.DISPLAY_NAME, fileName);
values.put(Images.Media.DESCRIPTION, fileName);

Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
//where app_id is the application ID, find the ID
//by clicking on your application on Market home
//page, and notice the ID from the address bar
刚才找app id未果,结果发现用package name也可以
Uri uri = Uri.parse("market://details?id=<packagename>");
这个简单多了
17寻找应用
Uri uri = Uri.parse("market://search?q=pname:pkg_name");
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
//where pkg_name is the full package path for an application
18打开联系人列表
<1>
Intent i = new Intent();
i.setAction(Intent.ACTION_GET_CONTENT);
i.setType("vnd.android.cursor.item/phone");
startActivityForResult(i, REQUEST_TEXT);
<2>
Uri uri = Uri.parse("content://contacts/people");
Intent it = new Intent(Intent.ACTION_PICK, uri);
startActivityForResult(it, REQUEST_TEXT);
19 打开另一程序
Intent i = new Intent();
ComponentName cn = new ComponentName("com.yellowbook.android2",
"com.yellowbook.android2.AndroidSearch");
i.setComponent(cn);
i.setAction("android.intent.action.MAIN");
startActivityForResult(i, RESULT_OK);
