自定义音乐+广播

自定义适配器

public class LAdapter extends BaseAdapter{

//创建属性
private Context context;
//对象
private ArrayList<Music> list;

//有参构造
public LAdapter(Context context, ArrayList<Music> list) {
	super();
	this.context = context;
	this.list = list;
}

@Override
public int getCount() {
	// TODO Auto-generated method stub
	return list.size();
}

@Override
public Object getItem(int position) {
	// TODO Auto-generated method stub
	return list.get(position);
}

@Override
public long getItemId(int position) {
	// TODO Auto-generated method stub
	return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
	// TODO Auto-generated method stub
	//优化
	ViewHolder holder=null;
	if(convertView==null){
		holder=new ViewHolder();
		convertView = View.inflate(context, R.layout.list, null);
		
		holder.image=(ImageView) convertView.findViewById(R.id.image1);
		holder.name=(TextView) convertView.findViewById(R.id.name1);
		holder.singer=(TextView) convertView.findViewById(R.id.singer1);
		
		convertView.setTag(holder);
		
	}else{
		holder=(ViewHolder) convertView.getTag();
		
	}
	Music music = list.get(position);
	holder.image.setImageResource(music.getImage1());
	holder.name.setText(music.getName());
	holder.singer.setText(music.getSinger());
	return convertView;
}

//自定义viewholder类
class ViewHolder{
	ImageView image;
	TextView name,singer;
	
}

}

自定义Music类

public class Music implements Serializable{

private int image1;
private String name;
private String singer;

private File file;

public Music() {
	super();
	// TODO Auto-generated constructor stub
}

public Music(int image1, String name, String singer, File file) {
	super();
	this.image1 = image1;
	this.name = name;
	this.singer = singer;
	this.file = file;
}

public int getImage1() {
	return image1;
}

public void setImage1(int image1) {
	this.image1 = image1;
}

public String getName() {
	return name;
}

public void setName(String name) {
	this.name = name;
}

public String getSinger() {
	return singer;
}

public void setSinger(String singer) {
	this.singer = singer;
}

public File getFile() {
	return file;
}

public void setFile(File file) {
	this.file = file;
}

@Override
public String toString() {
	return "Music [image1=" + image1 + ", name=" + name + ", singer="
			+ singer + ", file=" + file + "]";
}

}

自定义广播类

//开机自启
public class MyReceiver extends BroadcastReceiver{

@Override
public void onReceive(Context context, Intent intent) {
	// TODO Auto-generated method stub
	//进入方法
	if("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())){
		//创建intent
		Intent data = new Intent(context,MainActivity.class);
		data.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		//跳转
		context.startActivity(data);
	}
	
	
}

}
