3-2 creating a clip tag file

<?xml version= "1.0" encoding= "Utf-8"? ><clip xmlns:android= "Http://schemas.android.com/apk/res/android"    android:cliporientation= "Horizontal"    android:drawable= "@drawable/progress_v_01"    android:gravity= " Center_horizontal "    ></clip>

Cliporientation Setting the orientation to the horizontal direction

Gravity Alignment for vertical center alignment (resulting in an implementation that extends the progress from the middle to the sides)

3-3 using the same 1-3 in the layout file;

3-4 settings in Java code are the same as 1-4;

4. Horizontal-to-right circular progress bar

4-1 define the graphical Drawbale directory used to display the progress of Progress_oval_01.xml

<?xml version= "1.0" encoding= "Utf-8"? ><shape xmlns:android= "Http://schemas.android.com/apk/res/android"    android:shape= "Oval" >    <!--Set the night display size-    <size        android:width= "100DP"        android: height= "100DP"/>    <!--set Graphics color-    <gradient        android:centercolor= "#CC9933"        android: centerx= "0.5"        android:centery= "0.5"        android:endcolor= "#33FF33"        android:gradientradius= "45"        android:startcolor= "#FFFF33"        android:type= "radial"/>    <!--set graphics border--    <stroke        android:width= "2DP"        android:color= "#0000CC"/>    </shape>

4-2 creating a clip file to use

<?xml version= "1.0" encoding= "Utf-8"? ><clip xmlns:android= "Http://schemas.android.com/apk/res/android"    android:cliporientation= "Horizontal"    android:drawable= "@drawable/progress_oval_01"    android: Gravity= "left"    ></clip>

Cliporientation Setting the orientation to the horizontal direction

Gravity alignment is left aligned during setup (thus achieving progress from left-to-right extension of the implementation effect)

3-3 using the same 1-3 in the layout file;

3-4 settings in Java code are the same as 1-4;

5. Center outward-expanding circular progress bar

5-1 Create a graph that shows progress here is a reference to the graphics created in 4-1

5-2 Creating a clip label file for the display

<?xml version= "1.0" encoding= "Utf-8"? ><clip xmlns:android= "Http://schemas.android.com/apk/res/android"    android:cliporientation= "horizontal|vertical"    android:drawable= "@drawable/progress_oval_01"    android:gravity= "Center"    ></clip>

Cliporientation Setting the orientation to the horizontal direction

Gravity alignment is centered during setup (thus achieving an extended implementation of progress from the middle to the sides)

5-3 using the same 1-3 in the layout file;

Create ImageView tag, reference under SRC attribute

5-4 settings in Java code are the same as 1-4;

6. Vertical upward straight line progress bar

6-1 creating a graph showing progress

<?xml version= "1.0" encoding= "Utf-8"? ><shape xmlns:android= "Http://schemas.android.com/apk/res/android"    android:shape= "Rectangle"    >    <size android:width= "5DP"        android:height= "100DP"/>    <gradient        android:angle= "android:startcolor="        #FF9900 "        android:centercolor=" #FFFF00 "        Android:endcolor= "#66FF00"        />    <corners android:radius= "5DP"/></shape>

: 6-1-1

6-2 creating the corresponding clip tag file

<?xml version= "1.0" encoding= "Utf-8"? ><clip xmlns:android= "Http://schemas.android.com/apk/res/android"    android:cliporientation= "vertical"    android:drawable= "@drawable/progress_oval_01"    android:gravity= "Bottom"    ></clip>

Cliporientation Setting the orientation to the vertical direction

Gravity the alignment at the bottom of the setup process (thus achieving the effect of increasing the progress from the bottom up)

If set to top, then the progress will be from top to bottom

6-3 using the same 1-3 in the layout file;

Create ImageView tag, reference under SRC attribute

6-4 settings in Java code are the same as 1-4;

7. Vertical Upward circular progress bar

the clipdrawable represents a "picture fragment" from another bitmap. Use the <clip.../> element to define the Clipdrawable object in the XML file. The following three properties can be specified:

Android:drawable: Specifies the intercepted source drawable object, or you can specify a child label for the Drawable class

android:cliporientation: Specifies the direction of interception, which can be set to horizontal vertical

android:gravity: Specifies the alignment at intercept, can be set to top bottom right center_vertical fill_vertical center_horizontal Center fill Clip_ Vertaical start end and so on

You can use the Clipdrawable object to call the Setlevel (int level) method to set the size of the intercept, and when level is 0 o'clock, the captured picture fragment is empty, and when level is 10000, the entire picture is truncated.

You can use the CLIThis nature of pdrawable controls the size of the captured image area, allowing the program to constantly call the Setlevel method and change the level value, so that the image slowly expand the effect
