Android 项目统一日志文件配置, 这样可以方便管理，统一日志打印格式，在项目最后release 的也方便关闭日志。

package com.ben.log; import android.app.Activity; import android.content.Context; import android.util.Log; import android.widget.Toast; /** * Log助手 */ public class HLog { private static Toast mToast; private static final boolean DEBUG = true;//测试打印 public static void showToast(Context context, int resId, int duration) { if (mToast == null) { mToast = Toast.makeText(context, context.getString(resId), duration); } else { mToast.setText(context.getString(resId)); } mToast.show(); } public static void showToast(Context context, String msg, int duration) { if (mToast == null) { mToast = Toast.makeText(context, msg, duration); } else { mToast.setText(msg); } mToast.show(); } public static void i(String TAG, String methodName, String msg) { if (DEBUG) { Log.i(TAG "-->", methodName "-->" msg); } } public static void d(String TAG, String methodName, String msg) { if (DEBUG) { Log.d(TAG "-->", methodName "-->" msg); } } public static void w(String TAG, String methodName, String msg) { if (DEBUG) { Log.w(TAG "-->", methodName "-->" msg); } } public static void e(String TAG, String methodName, String msg) { if (DEBUG) { Log.e(TAG "-->", methodName "-->" msg); } } public static void v(String TAG, String methodName, String msg) { if (DEBUG) { Log.v(TAG "-->", methodName "-->" msg); } } public static void toast(Context context, String text) { if (mToast == null) { mToast = Toast.makeText(context, text, Toast.LENGTH_SHORT); } else { mToast.setText(text); } mToast.show(); } public static void toast(Context context, int resId) { if (mToast == null) { mToast = Toast.makeText(context, context.getString(resId), Toast.LENGTH_LONG); } else { mToast.setText(context.getString(resId)); } mToast.show(); } public static void toastOnUI(final Activity activity, final int resId) { activity.runOnUiThread(new Runnable() { @Override public void run() { if (mToast == null) { mToast = Toast.makeText(activity, activity.getString(resId), Toast.LENGTH_LONG); } else { mToast.setText(activity.getString(resId)); } mToast.show(); } }); } /** *toast取消 */ public static void cancel() { if (mToast != null) { mToast.cancel(); mToast = null; } } }
