Android基础项目手机卫士总结

智慧北京.note//设置一个没有标题的activity

requestWindowFeature(Window.FEATURE_NO_TITLE);

设置自己的版本号

PackageManager pm = getPackageManager();

try {

PackageInfo packageInfo = pm.getPackageInfo(this.getPackageName(), 0);

versionName = packageInfo.versionName;

} catch (PackageManager.NameNotFoundException e) {

e.printStackTrace();

}

安装指定的apk

//一种隐式调用

Intent intent = new Intent("android.intent.action.VIEW");

intent.addCategory("android.intent.category.DEFAULT");

intent.setData(Uri.fromFile(file));

intent.setType("application/vnd.android.package-archive");

intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");

startActivityForResult(intent,0);

查询电话号码

ContentResolver contentResolver = getContentResolver();

//做查询过程

Cursor query = contentResolver.query(Uri.parse("content://com.android.contacts/raw_contacts"), new String[]{"contact_id"}, null, null, null);

contactList.clear();

while (query.moveToNext()) {

String id = query.getString(0);

Cursor indexCursor = contentResolver.query(Uri.parse("content://com.android.contacts/data"), new String[]{"data1", "mimetype"}, "raw_contact_id=?", new String[]{id}, null);

HashMap hashMap = new HashMap();

while (indexCursor.moveToNext()) {

String data = indexCursor.getString(0);

String type = indexCursor.getString(1);

if (type.equals("vnd.android.cursor.item/phone_v2")) {

if (!TextUtils.isEmpty(data)) {

if (!(data==null)){

if (!data.equals("")){

hashMap.put("phone", data);

}

}

}

} else if (type.equals("vnd.android.cursor.item/name")) {

if (!TextUtils.isEmpty(data)) {

if (!(data==null)){

if (!data.equals("")){

hashMap.put("name", data);

}

}

}

}

}

contactList.add(hashMap);

indexCursor.close();

}

query.close();

mHhandler.sendEmptyMessage(0);

}

拿到手机的内存大小

tv_memory.setText("磁盘内存"+memoryAvailSpace);

}

private long getAvailSpace(String path) {

//拿到内存的块数 和每一个的大小然后相乘

StatFs statFs=new StatFs(path);

//拿到块数

long block = statFs.getAvailableBlocks();

//拿到每一块的大小

long size = statFs.getBlockSize();

return block*size;

}

//这是一种悬浮的窗口
