以下內(nèi)容來自多個(gè)開源項(xiàng)目的整理和自己的項(xiàng)目積累。
1.收集設(shè)備信息颤枪，用于信息統(tǒng)計(jì)分析
public static Properties collectDeviceInfo(Context context) {
Properties mDeviceCrashInfo = new Properties();
try {
PackageManager pm = context.getPackageManager();
PackageInfo pi = pm.getPackageInfo(context.getPackageName(),
PackageManager.GET_ACTIVITIES);
if (pi != null) {
mDeviceCrashInfo.put(VERSION_NAME,
pi.versionName == null ? "not set" : pi.versionName);
mDeviceCrashInfo.put(VERSION_CODE, pi.versionCode);
}
} catch (PackageManager.NameNotFoundException e) {
Log.e(TAG, "Error while collect package info", e);
}
Field[] fields = Build.class.getDeclaredFields();
for (Field field : fields) {
try {
field.setAccessible(true);
mDeviceCrashInfo.put(field.getName(), field.get(null));
} catch (Exception e) {
Log.e(TAG, "Error while collect crash info", e);
}
}
return mDeviceCrashInfo;
}
public static String collectDeviceInfoStr(Context context) {
Properties prop = collectDeviceInfo(context);
Set deviceInfos = prop.keySet();
StringBuilder deviceInfoStr = new StringBuilder("{\n");
for (Iterator iter = deviceInfos.iterator(); iter.hasNext();) {
Object item = iter.next();
deviceInfoStr.append("\t\t\t" + item + ":" + prop.get(item)
+ ", \n");
}
deviceInfoStr.append("}");
return deviceInfoStr.toString();
}
2.是否有SD卡
public static boolean haveSDCard() {
return android.os.Environment.getExternalStorageState().equals(
android.os.Environment.MEDIA_MOUNTED);
}
3.動態(tài)隱藏軟鍵盤
@TargetApi(Build.VERSION_CODES.CUPCAKE)
public static void hideSoftInput(Activity activity) {
View view = activity.getWindow().peekDecorView();
if (view != null) {
InputMethodManager inputmanger = (InputMethodManager) activity
.getSystemService(Context.INPUT_METHOD_SERVICE);
inputmanger.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
@TargetApi(Build.VERSION_CODES.CUPCAKE)
public static void hideSoftInput(Context context, EditText edit) {
edit.clearFocus();
InputMethodManager inputmanger = (InputMethodManager) context
.getSystemService(Context.INPUT_METHOD_SERVICE);
inputmanger.hideSoftInputFromWindow(edit.getWindowToken(), 0);
}
4.動態(tài)顯示軟鍵盤
@TargetApi(Build.VERSION_CODES.CUPCAKE)
public static void showSoftInput(Context context, EditText edit) {
edit.setFocusable(true);
edit.setFocusableInTouchMode(true);
edit.requestFocus();
InputMethodManager inputManager = (InputMethodManager) context
.getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.showSoftInput(edit, 0);
}
5.動態(tài)顯示或者是隱藏軟鍵盤
@TargetApi(Build.VERSION_CODES.CUPCAKE)
public static void toggleSoftInput(Context context, EditText edit) {
edit.setFocusable(true);
edit.setFocusableInTouchMode(true);
edit.requestFocus();
InputMethodManager inputManager = (InputMethodManager) context
.getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}
6.主動回到Home汗捡，后臺運(yùn)行
public static void goHome(Context context) {
Intent mHomeIntent = new Intent(Intent.ACTION_MAIN);
mHomeIntent.addCategory(Intent.CATEGORY_HOME);
mHomeIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
context.startActivity(mHomeIntent);
}
7.獲取狀態(tài)欄高度
注意，要在onWindowFocusChanged中調(diào)用畏纲，在onCreate中獲取高度為0
@TargetApi(Build.VERSION_CODES.CUPCAKE)
public static int getStatusBarHeight(Activity activity) {
Rect frame = new Rect();
activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
return frame.top;
}
8.獲取狀態(tài)欄高度＋標(biāo)題欄(ActionBar)高度
(注意扇住，如果沒有ActionBar，那么獲取的高度將和上面的是一樣的盗胀，只有狀態(tài)欄的高度)
public static int getTopBarHeight(Activity activity) {
return activity.getWindow().findViewById(Window.ID_ANDROID_CONTENT)
.getTop();
}
9.獲取MCC+MNC代碼 (SIM卡運(yùn)營商國家代碼和運(yùn)營商網(wǎng)絡(luò)代碼)
僅當(dāng)用戶已在網(wǎng)絡(luò)注冊時(shí)有效, CDMA 可能會無效（中國移動：46000 46002, 中國聯(lián)通：46001,中國電信：46003）
public static String getNetworkOperator(Context context) {
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
return telephonyManager.getNetworkOperator();
}
10.返回移動網(wǎng)絡(luò)運(yùn)營商的名字
(例：中國聯(lián)通台囱、中國移動、中國電信) 僅當(dāng)用戶已在網(wǎng)絡(luò)注冊時(shí)有效, CDMA 可能會無效)
public static String getNetworkOperatorName(Context context) {
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
return telephonyManager.getNetworkOperatorName();
}
11.返回移動終端類型
PHONE_TYPE_NONE :0 手機(jī)制式未知
PHONE_TYPE_GSM :1 手機(jī)制式為GSM读整，移動和聯(lián)通
PHONE_TYPE_CDMA :2 手機(jī)制式為CDMA，電信
PHONE_TYPE_SIP:3
public static int getPhoneType(Context context) {
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
return telephonyManager.getPhoneType();
}
12.判斷手機(jī)連接的網(wǎng)絡(luò)類型(2G,3G,4G)
聯(lián)通的3G為UMTS或HSDPA咱娶，移動和聯(lián)通的2G為GPRS或EGDE米间，電信的2G為CDMA，電信的3G為EVDO
public class Constants {
/**
* Unknown network class
*/
public static final int NETWORK_CLASS_UNKNOWN = 0;
/**
* wifi net work
*/
public static final int NETWORK_WIFI = 1;
/**
* "2G" networks
*/
public static final int NETWORK_CLASS_2_G = 2;
/**
* "3G" networks
*/
public static final int NETWORK_CLASS_3_G = 3;
/**
* "4G" networks
*/
public static final int NETWORK_CLASS_4_G = 4;
}
public static int getNetWorkClass(Context context) {
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
switch (telephonyManager.getNetworkType()) {
case TelephonyManager.NETWORK_TYPE_GPRS:
case TelephonyManager.NETWORK_TYPE_EDGE:
case TelephonyManager.NETWORK_TYPE_CDMA:
case TelephonyManager.NETWORK_TYPE_1xRTT:
case TelephonyManager.NETWORK_TYPE_IDEN:
return Constants.NETWORK_CLASS_2_G;
case TelephonyManager.NETWORK_TYPE_UMTS:
case TelephonyManager.NETWORK_TYPE_EVDO_0:
case TelephonyManager.NETWORK_TYPE_EVDO_A:
case TelephonyManager.NETWORK_TYPE_HSDPA:
case TelephonyManager.NETWORK_TYPE_HSUPA:
case TelephonyManager.NETWORK_TYPE_HSPA:
case TelephonyManager.NETWORK_TYPE_EVDO_B:
case TelephonyManager.NETWORK_TYPE_EHRPD:
case TelephonyManager.NETWORK_TYPE_HSPAP:
return Constants.NETWORK_CLASS_3_G;
case TelephonyManager.NETWORK_TYPE_LTE:
return Constants.NETWORK_CLASS_4_G;
default:
return Constants.NETWORK_CLASS_UNKNOWN;
}
}
13.判斷當(dāng)前手機(jī)的網(wǎng)絡(luò)類型(WIFI還是2,3,4G)
需要用到上面的方法:
public static int getNetWorkStatus(Context context) {
int netWorkType = Constants.NETWORK_CLASS_UNKNOWN;
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
if (networkInfo != null && networkInfo.isConnected()) {
int type = networkInfo.getType();
if (type == ConnectivityManager.TYPE_WIFI) {
netWorkType = Constants.NETWORK_WIFI;
} else if (type == ConnectivityManager.TYPE_MOBILE) {
netWorkType = getNetWorkClass(context);
}
}
return netWorkType;
}
