Android开发常用工具类与资源

常用初始化类

public class ContextUtils extends Application {
/* 获取context */
private static ContextUtils instance;

public static ContextUtils getInstance() {
return instance;
}

@Override
public void onCreate() {
super.onCreate();
instance = this;
initValue();
}

public void initValue() {
//LogUtils.DEBUG = true;
}
}

<application
android:name=".util.ContextUtils"
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

常用日志工具类

public class LogUtils {

public static boolean DEBUG;

public static void v(String msg) {
if (DEBUG)
Log.v(getMethodPath(4, 4), msg);
}

public static void i(String msg) {
if (DEBUG)
Log.i(getMethodPath(4, 4), msg);
}

public static void d(String msg) {
if (DEBUG)
Log.d(getMethodPath(4, 4), msg);
}

public static void w(String msg) {
if (DEBUG)
Log.w(getMethodPath(4, 4), msg);
}

public static void e(String msg) {
if (DEBUG)
Log.e(getMethodPath(4, 4), msg);
}

/**
* 得到调用此方法的类名与方法名，默认下标为3
* @return string
*/
public static String getMethodPath() {
return Thread.currentThread().getStackTrace()[3].getClassName() + "."
+ Thread.currentThread().getStackTrace()[3].getMethodName() + "-->";
}

/**
* 得到调用此方法的类名与方法名
* @param classPrior 类级
* @param methodPrior 方法级
* @return string
*/
public static String getMethodPath(int classPrior, int methodPrior) {
int length = Thread.currentThread().getStackTrace().length;
if (classPrior > length || methodPrior > length) {
return null;
} else
return Thread.currentThread().getStackTrace()[classPrior].getClassName() + "."
+ Thread.currentThread().getStackTrace()[methodPrior].getMethodName() + "-->";
}

/**
* 测试方法，将线程中的序列全部输出
*/
public static void logThreadSequence() {
int length = Thread.currentThread().getStackTrace().length;
for (int i = 0; i < length; i++) {
Log.i(Thread.currentThread().getStackTrace()[i].getClassName(),
Thread.currentThread().getStackTrace()[i].getMethodName());
}
}
}
