Progressbar-style attribute Analysis

First, let's look at the style definition for the progress bar under the framework, as follows

    <stylename= "Widget.progressbar">        <Itemname= "Android:indeterminateonly">True</Item>        <Itemname= "Android:indeterminatedrawable">@android:d Rawable/progress_medium_white</Item>        <Itemname= "Android:indeterminatebehavior">Repeat</Item>        <Itemname= "Android:indeterminateduration">3500</Item>        <Itemname= "Android:minwidth">48dip</Item>        <Itemname= "Android:maxwidth">48dip</Item>        <Itemname= "Android:minheight">48dip</Item>        <Itemname= "Android:maxheight">48dip</Item>        <Itemname= "Android:mirrorforrtl">False</Item>

For the above attribute, the meaning is as follows

Property name	Describe
Android:animationresolution	The milliseconds between the time-out animation frames, which must be an integer value, such as "100".
Android:indeterminate	Whether to allow the use of indeterminate mode, in the indeterminate mode, the progress bar animation Infinite loop
Android:indeterminatebehavior	Define the performance of the indeterminate pattern when the progress is maximized; The value must be repeat or cycle,repeat to indicate that the progress is starting from 0, and that cycle indicates that the progress remains current and goes back to 0
Android:indeterminatedrawable	Defines whether the indeterminate mode can be pulled
Android:indeterminateduration	Time-Varying animations
Android:indeterminateonly	Limit to indeterminate mode
Android:interpolator
Android:max	Define the maximum value of the progress
Android:maxheight	Maximum Progress widget height
Android:miniheight	Progress widget min. high
Android:maxwidth	Maximum Progress widget width
Android:minwidth	Progress widget min. width
Android:mirrorforrtl	Defines the relevant artboard if needed to be reflected in RTL mode
Android:progress	Set the default value for progress from 0 to Max
Android:progressdrawable
Android:secondaryprogress	Defines a level two progress value ranging from 0 to max. The progress is between the master progress and the background. For example, for network playback video, level two progress is used to represent the buffering progress, and the master progress is used to indicate the playback progress.

Let's see what's the difference between the MaxHeight property and the Layout_height in ProgressBar.

The code is as follows

   <ProgressBarAndroid:id= "@+id/stateprogressbar"android:orientation= "Horizontal"Android:layout_width= "Match_parent"Android:layout_height= "200DP"Android:max= "+"android:progress= "Ten"Android:background= "#00ffff"android:secondaryprogress= " the"Android:layout_margintop= "4dip"style= "@style/play_progressbar"/>

The code for style is as follows

    <stylename= "Play_progressbar"Parent= "@android: Style/widget.holo.light.progressbar.horizontal">        <Itemname= "Android:progressdrawable">@drawable/progress_horizontal_holo_dark</Item>        <Itemname= "Android:minheight">50dp</Item>        <Itemname= "Android:maxheight">50dp</Item>        <!--Item Name= "android:indeterminatedrawable" > @drawable/progress_indeterminate_horizontal_holo</item  -    </style>

Run results

We can see that Layout_height has a role, and that the progress bar is filled with the entire ProgressBar

When Max is bigger than PROGRESSBA,

   <ProgressBarAndroid:id= "@+id/stateprogressbar"android:orientation= "Horizontal"Android:layout_width= "Match_parent"Android:layout_height= "50DP"Android:max= "+"android:progress= "Ten"Android:background= "#00ffff"android:secondaryprogress= " the"Android:layout_margintop= "4dip"style= "@style/play_progressbar"/>

Style

    <stylename= "Play_progressbar"Parent= "@android: Style/widget.holo.light.progressbar.horizontal">        <Itemname= "Android:progressdrawable">@drawable/progress_horizontal_holo_dark</Item>        <Itemname= "Android:minheight">200dp</Item>        <Itemname= "Android:maxheight">200dp</Item>        <!--Item Name= "android:indeterminatedrawable" > @drawable/progress_indeterminate_horizontal_holo</item -    </style>

Run results

Proves again that the correctness of the above statement
