Android ProgressBar UI 自定义布局 [英] Android ProgressBar UI custom layout

问题描述

我正在尝试自定义一个状态栏，使其看起来像这个图像:

I am trying to customize a status bar so it will look like this image:

然而，几个小时后，我只有一个状态栏，我只需要背景(图 2):

However, after a good couple of hours all I have is a status bar with the background I need only (Image 2):

我目前的代码是:xml布局:

The current code I have is: xml layout:

<ProgressBar
                android:id="@+id/pBarOverallStatus"
                style="?android:attr/progressBarStyleHorizontal"
                android:layout_width="0dip"
                android:layout_height="fill_parent"
                android:layout_marginLeft="10dip"
                android:layout_marginRight="10dip"
                android:layout_weight="94"
                android:indeterminateOnly="false"
                android:max="100"
                android:progressDrawable="@drawable/progress_bar_states" >
            </ProgressBar>

progress_bar_states.xml:

The progress_bar_states.xml:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <!-- <item android:id="@android:id/progress">
        <bitmap
            android:gravity="center"
            android:src="@drawable/progressbar_progressing" />

        <corners android:radius="10dp" />
    </item>
     -->

</layer-list>

删除评论，其中 proressbar_progressing 看起来像然后我有一些难看的东西，因为没有角落.

Removing the comment, where proressbar_progressing looks like then I am having something a bit ugly as there are no corners.

我正在从代码中添加背景，例如:

I am adding the background from code, something like:

overallStatus = (ProgressBar) findViewById(R.id.pBarOverallStatus);
Resources res = getResources();
overallStatus.setBackgroundDrawable(res.getDrawable(R.drawable.progressbar_background));
overallStatus.setProgress(50);

我尝试为图像添加角，但没有成功.有人知道我在这里做错了什么吗?或者我错过了什么?另外，您知道如何添加左右环吗?资源:

I tried to add corners to the image but no luck. Does anybody have any idea what I am doing wrong here? Or what am I missing? Also, do you have any idea how could I add the left and right rings? The resource:

推荐答案

解决方案(回答你自己的感觉很奇怪):首先，一个问题是进度可绘制与背景的大小不同(愚蠢的我！).此外，对于可绘制的进度，需要一个剪辑 xml.类似于progressbar_progress_clip.xml:

The solution (feels weird answering your own): First, one problem was that progress drawable had a different size than background (stupid me!). Also, for progress drawable a clip xml was needed. Something like progressbar_progress_clip.xml:

<?xml version="1.0" encoding="utf-8"?>
<clip
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/progressbar_progressing"
    android:clipOrientation="horizontal"
    android:gravity="left"/>

然后，将进度条和两张图片相对布局添加，这样图片就可以在状态栏之后绘制了.像这样:

Then, add the progress bar and two images in a relative layout, so that the images can be drawn after the status bar. Something like this:

<RelativeLayout
                android:id="@+id/relativeLayout1"
                android:layout_width="0dip"
                android:layout_height="fill_parent"
                android:layout_marginLeft="10dip"
                android:layout_marginRight="10dip"
                android:layout_weight="94" >

                <ProgressBar
                    android:id="@+id/pBarOverallStatus"
                    style="?android:attr/progressBarStyleHorizontal"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"
                    android:layout_marginBottom="2dp"
                    android:layout_marginTop="2dp"
                    android:indeterminateOnly="false"
                    android:max="100"
                    android:progressDrawable="@drawable/progressbar_progress_clip" >
                </ProgressBar>

                <ImageView
                    android:id="@+id/ringLeft"
                    android:layout_width="wrap_content"
                    android:layout_height="fill_parent"
                    android:layout_alignParentLeft="true"
                    android:layout_centerVertical="true"
                    android:layout_marginLeft="7dp"
                    android:contentDescription="@string/status_bar_ring"
                    android:src="@drawable/status_bar_ring" />

                <ImageView
                    android:id="@+id/ringRight"
                    android:layout_width="wrap_content"
                    android:layout_height="fill_parent"
                    android:layout_alignParentRight="true"
                    android:layout_centerVertical="true"
                    android:layout_marginRight="7dp"
                    android:contentDescription="@string/status_bar_ring"
                    android:src="@drawable/status_bar_ring" />
            </RelativeLayout>
