常用代码：收集设备信息+有无SD卡+软键盘+Home，后台运行+状态栏高度＋标题栏(ActionBar)高+SIM卡+网路

拨打电话

public static void call(Context context, String phoneNumber) {
context.startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber)));
}

跳转至拨号界面

public static void sendSms(Context context, String phoneNumber,
String content) {
Uri uri = Uri.parse("smsto:"
+ (TextUtils.isEmpty(phoneNumber) ? "" : phoneNumber));
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
intent.putExtra("sms_body", TextUtils.isEmpty(content) ? "" : content);
context.startActivity(intent);
}

唤醒屏幕并解锁

public static void wakeUpAndUnlock(Context context){
KeyguardManager km= (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
KeyguardManager.KeyguardLock kl = km.newKeyguardLock("unLock");
//解锁
kl.disableKeyguard();
//获取电源管理器对象
PowerManager pm=(PowerManager) context.getSystemService(Context.POWER_SERVICE);
//获取PowerManager.WakeLock对象,后面的参数|表示同时传入两个值,最后的是LogCat里用的Tag
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK,"bright");
//点亮屏幕
wl.acquire();
//释放
wl.release();

@SuppressWarnings("deprecation")
List<ActivityManager.RunningTaskInfo> tasks = am.getRunningTasks(1);
if (!tasks.isEmpty()) {
ComponentName topActivity = tasks.get(0).topActivity;
if (!topActivity.getPackageName().equals(context.getPackageName())) {
return true;
}
}
return false;
}

需要添加权限

<uses-permission
android:name="android.permission.GET_TASKS" />

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.动态隐藏软键盘

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.动态显示软键盘

@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.动态显示或者是隐藏软键盘

@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.主动回到Home，后台运行

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.获取状态栏高度
注意，要在

onWindowFocusChanged

中调用，在onCreate中获取高度为

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.获取状态栏高度＋标题栏(ActionBar)高度
(注意，如果没有ActionBar，那么获取的高度将和上面的是一样的，只有状态栏的高度)

public static int getTopBarHeight(Activity activity) {
return activity.getWindow().findViewById(Window.ID_ANDROID_CONTENT)
.getTop();
}

9.获取MCC+MNC代码 (SIM卡运营商国家代码和运营商网络代码)
仅当用户已在网络注册时有效, CDMA 可能会无效（中国移动：46000 46002, 中国联通：46001,中国电信：46003）

public static String getNetworkOperator(Context context) {
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
return telephonyManager.getNetworkOperator();
}

10.返回移动网络运营商的名字
(例：中国联通、中国移动、中国电信) 仅当用户已在网络注册时有效, CDMA 可能会无效)

public static String getNetworkOperatorName(Context context) {
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
return telephonyManager.getNetworkOperatorName();
}

11.返回移动终端类型
PHONE_TYPE_NONE :0 手机制式未知

PHONE_TYPE_GSM :1 手机制式为GSM，移动和联通

PHONE_TYPE_CDMA :2 手机制式为CDMA，电信

PHONE_TYPE_SIP:3

public static int getPhoneType(Context context) {
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
return telephonyManager.getPhoneType();
}

12.判断手机连接的网络类型(2G,3G,4G)
联通的3G为UMTS或HSDPA，移动和联通的2G为GPRS或EGDE，电信的2G为CDMA，电信的3G为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.判断当前手机的网络类型(WIFI还是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;
}
