1.点击一个按钮跳转到百度页面（或者另一个activity）：public class MainActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState

记录下自己实现的一个通用弹窗，使用的时候传入自己需要的view即可public class PopWindow { private Activity mContext; private ViewGroup contentView; private PopupWindow popupWindow; public interface OnPopWindowDi

1.报错：10-29 10:17:23.960 5768-5788/com.coocaa.mall E/APP_CRASH: java.lang.RuntimeException: Failure during heap dump; check log output for details

public class StandardView extends LinearLayout { private Context mContext; private TextView standard; private LinearLayout.LayoutParams lp; private Drawable standardLeftIcon, standardR

比如：取这个地址“"http://blog.youkuaiyun.com/meetings/article/details/78785424"”里的“blog.youkuaiyun.com”对应的真实IP /** * 获取url对应的域名 * * @param url * @return */ public String getDomain(String

/** * 获取安卓设备当前的IP地址（有线或无线） * * @return */ private String getClientIP() { try { // 获取本地设备的所有网络接口 Enumeration enumerationNi = NetworkInterface

1.效果图：2.自定义view实现public class UniformLine extends View { private int x, y, nextX, nextY, incrementY, incrementX; public UniformLine(Context context) { super(context); }

1.效果图                       2.代码实现public class PieChartView extends View { private Paint mPaint; private ListpieDataList; // 饼状图初始绘制角度 private float mStartAngle = 0; public

1、效果图2、帧动画的简要代码 private ImageView bgAnimView; private AnimationDrawable mAnimationDrawable; //初始化 mAnimationDrawable = new AnimationDrawable(); bgAnimView = new ImageV

startActivity时错误信息提示：android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want? 原来是

有时候我们在和后台约定请求参数的时候会涉及到编码解码的问题，但是retrofit里面默认的编码方式很可能和后台的解码方式不一致，导致前端请求不到数据： try { extendStr = URLEncoder.encode(param,"utf-8"); } catch (UnsupportedEncodingException e) {

private SimpleDraweeView draweeView; draweeView = (SimpleDraweeView) findViewById(R.id.gif); draweeView.setController(getDraweeController(R.drawable.gif1)); draweeView.setOnClickListener(o

1.ContentObserver简单介绍：    ContentObserver——内容观察者，目的是观察(捕捉)特定Uri引起的数据库的变化，继而做一些相应的处理，它类似于数据库技术中的触发器(Trigger)，当ContentObserver所观察的Uri发生变化时，便会触发它。2.编程步骤：    ①创建我们特定的ContentObserver派生类，必须重载父类构造方法，

1.最常见用法：子控件的宽度比是1：2：3<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height=

1.同步get请求：传统方式： URL url = null; try { url = new URL(_url); HttpURLConnection urlConn = null; urlConn = (HttpURLConnection) url.openConnection(); // 设置连接超时时间

1.核心： 一个方法类(HttpMethod)+一个接口(HttpService)public class ADHttpMethods { public static final String BASE_URL = "http://172.20.132.196:1660/i/"; private Retrofit retrofit; private ADHttpSer

传：Intent adIntent = new Intent();adIntent.putExtra("app", app);adIntent.putExtra("space", space);Bundle b = new Bundle();b.putParcelable("eIntent", intent);adIntent.putExtras(b);context.startA

新加两个类即可：MigrationHelper 和 MyOpenHelper/** * Created by fc on 2017/4/7. */public class MigrationHelper { private static final String CONVERSION_CLASS_NOT_FOUND_EXCEPTION = "MIGRA

删除两个%之间的所有字符： String s = "http://media.advu.cn/stat/index?f=1001&eventid=266&tvType=%appname%&appname=%apptype%&time=%time%"; String result = s.replaceAll("%[^%]*%", ""); Log.

一、简要概念：1.Mock的概念：mock就是创建一个类的虚假的对象，在测试环境中，用来替换掉真实的对象2.目的：①验证这个对象的某些方法的调用情况，调用了多少次，参数是什么等等②可以随时指定mock对象的某个方法返回什么样的值，或执行什么样的动作。Mockito.verify(mockUserManager, Mockito.times(3)).performLogin(..

1.效果图2.实现：path绘制直线+path绘制不规则图形(如果想要动态绘制，可以动态改变图形显示的LayoutParams)/** * Created by fc on 2018/5/7. * &lt;mPaint&gt; * 根据坐标系list来绘制折线 */public class PathLine extends View { private Paint mPaint...
