我正在尝试创建一个圆形的进度条。这就是我想要实现的目标
有一个灰色背景环。在它的顶部,会出现一个蓝色进度条,它在60或任何秒数内以0到360的圆形路径移动。
这是我的示例代码。
<ProgressBar
android:id="@+id/ProgressBar"
android:layout_width="match_parent"
android:layout_height="match_parent"
style="?android:attr/progressBarStyleLarge"
android:indeterminateDrawable="@drawable/progressBarBG"
android:progress="50"
/>
要做到这一点,在drawable“progressBarBG”中,我正在创建一个图层列表,在该图层列表中我给出了两个项目,如图所示。
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
<shape
android:shape="ring"
android:innerRadius="64dp"
android:thickness="8dp"
android:useLevel="false">
<solid android:color="@color/grey" />
</shape>
</item>
<item android:id="@android:id/progress">
<clip>
<shape
android:shape="ring"
android:innerRadius="64dp"
android:thickness="8dp"
android:useLevel="false">
<solid android:color="@color/blue" />
</shape>
</clip>
</item>
现在,第一个灰色环生成正常。然而,蓝色环从drawable的左侧开始向右移动,就像线性进度条的工作原理一样。这就是它显示50%进度的方式,红色箭头显示方向。
我想按预期在圆形路径中移动蓝色进度条。

以下是我的两个解决方案。
简答:
我没有创建layer-list
,而是将其分成两个文件。一个用于ProgressBar
,一个用于其背景。
这是ProgressDrawable
文件(@drawable文件夹): circular_progress_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="270"
android:toDegrees="270">
<shape
android:innerRadiusRatio="2.5"
android:shape="ring"
android:thickness="1dp"
android:useLevel="true"><!-- this line fixes the issue for lollipop api 21 -->
<gradient
android:angle="0"
android:endColor="#007DD6"
android:startColor="#007DD6"
android:type="sweep"
android:useLevel="false" />
</shape>
</rotate>
这是针对background
(@ drawable文件夹): circle_shape.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="ring"
android:innerRadiusRatio="2.5"
android:thickness="1dp"
android:useLevel="false">
<solid android:color="#CCC" />
</shape>
最后,在您正在工作的布局中:
<ProgressBar
android:id="@+id/progressBar"
android:layout_width="200dp"
android:layout_height="200dp"
android:indeterminate="false"
android:progressDrawable="@drawable/circular_progress_bar"
android:background="@drawable/circle_shape"
style="?android:attr/progressBarStyleHorizontal"
android:max="100"
android:progress="65" />
结果如下:
长答案:
使用继承android.view.View

我已经在我的博客circular progress bar in android上写了关于demonuts.com的详细示例。你也可以在那里喜欢完整的源代码和解释。
以下是我在没有任何库的纯代码中使用圆圈内百分比制作圆形进度条的方法。
首先创建一个名为circular.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/secondaryProgress">
<shape
android:innerRadiusRatio="6"
android:shape="ring"
android:thicknessRatio="20.0"
android:useLevel="true">
<gradient
android:centerColor="#999999"
android:endColor="#999999"
android:startColor="#999999"
android:type="sweep" />
</shape>
</item>
<item android:id="@android:id/progress">
<rotate
android:fromDegrees="270"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="270">
<shape
android:innerRadiusRatio="6"
android:shape="ring"
android:thicknessRatio="20.0"
android:useLevel="true">
<rotate
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" />
<gradient
android:centerColor="#00FF00"
android:endColor="#00FF00"
android:startColor="#00FF00"
android:type="sweep" />
</shape>
</rotate>
</item>
</layer-list>
现在在activity_main.xml
添加以下内容:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/dialog"
tools:context="com.example.parsaniahardik.progressanimation.MainActivity">
<ProgressBar
android:id="@+id/circularProgressbar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="250dp"
android:layout_height="250dp"
android:indeterminate="false"
android:max="100"
android:progress="50"
android:layout_centerInParent="true"
android:progressDrawable="@drawable/circular"
android:secondaryProgress="100"
/>
<ImageView
android:layout_width="90dp"
android:layout_height="90dp"
android:background="@drawable/whitecircle"
android:layout_centerInParent="true"/>
<TextView
android:id="@+id/tv"
android:layout_width="250dp"
android:layout_height="250dp"
android:gravity="center"
android:text="25%"
android:layout_centerInParent="true"
android:textColor="@color/colorPrimaryDark"
android:textSize="20sp" />
</RelativeLayout>
在activity_main.xml
我使用了一个白色背景的圆形图像来显示百分比周围的白色背景。这是图像:
您可以更改此图像的颜色,以围绕百分比文字设置自定义颜色。
现在最后将以下代码添加到MainActivity.java
:
import android.content.res.Resources;
import android.graphics.drawable.Drawable;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.animation.DecelerateInterpolator;
import android.widget.ProgressBar;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
int pStatus = 0;
private Handler handler = new Handler();
TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Resources res = getResources();
Drawable drawable = res.getDrawable(R.drawable.circular);
final ProgressBar mProgress = (ProgressBar) findViewById(R.id.circularProgressbar);
mProgress.setProgress(0); // Main Progress
mProgress.setSecondaryProgress(100); // Secondary Progress
mProgress.setMax(100); // Maximum Progress
mProgress.setProgressDrawable(drawable);
/* ObjectAnimator animation = ObjectAnimator.ofInt(mProgress, "progress", 0, 100);
animation.setDuration(50000);
animation.setInterpolator(new DecelerateInterpolator());
animation.start();*/
tv = (TextView) findViewById(R.id.tv);
new Thread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
while (pStatus < 100) {
pStatus += 1;
handler.post(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
mProgress.setProgress(pStatus);
tv.setText(pStatus + "%");
}
});
try {
// Sleep for 200 milliseconds.
// Just to display the progress slowly
Thread.sleep(8); //thread will take approx 1.5 seconds to finish
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
}
}

答案 3 :(得分:11)
我在GitHub CircularProgressBar上实现了一个开源库,它能够以最简单的方式完成您想要的工作:
要制作循环ProgressBar,请在布局XML中添加 CircularProgressBar ,并在投影机中添加 CircularProgressBar库,或者也可以通过Gradle抓取它:
compile 'com.mikhaellopez:circularprogressbar:1.0.0'
<com.mikhaellopez.circularprogressbar.CircularProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:background_progressbar_color="#FFCDD2"
app:background_progressbar_width="5dp"
app:progressbar_color="#F44336"
app:progressbar_width="10dp" />
您必须在XML中使用以下属性来更改CircularProgressBar。
<强>属性:强>
app:progress
(整数)&gt;&gt;默认为0 app:progressbar_color
(颜色)&gt;&gt;默认黑色app:background_progressbar_color
(颜色)&gt;&gt;默认灰色app:progressbar_width
(维度)&gt;&gt;默认7dp app:background_progressbar_width
(维度)&gt;&gt;默认3dp CircularProgressBar circularProgressBar = (CircularProgressBar)findViewById(R.id.yourCircularProgressbar);
circularProgressBar.setColor(ContextCompat.getColor(this, R.color.progressBarColor));
circularProgressBar.setBackgroundColor(ContextCompat.getColor(this, R.color.backgroundProgressBarColor));
circularProgressBar.setProgressBarWidth(getResources().getDimension(R.dimen.progressBarWidth));
circularProgressBar.setBackgroundProgressBarWidth(getResources().getDimension(R.dimen.backgroundProgressBarWidth));
int animationDuration = 2500; // 2500ms = 2,5s
circularProgressBar.setProgressWithAnimation(65, animationDuration); // Default duration = 1500ms

使用材料成分库,您可以使用 CircularProgressIndicator
:
类似的东西:
<com.google.android.material.progressindicator.CircularProgressIndicator
app:indicatorColor="@color/...."
app:trackColor="@color/...."
app:circularRadius="64dp"/>
您可以使用以下属性:
circularRadius
:定义圆形进度指示器的半径trackColor
:进度条的颜色。如果未定义,它将设置为indicatorColor
并应用主题中的android:disabledAlpha
。indicatorColor
:确定/不确定模式下用于指示器的单色。默认情况下,它使用主题原色使用progressIndicator.setProgressCompat((int) value, true);
更新指标中的值。
注意:它至少需要版本1.3.0-alpha04
。

我是新手,所以我无法发表评论,但想过分享这个懒惰的修复方法。我也使用了Pedram的原创方法,并遇到了同样的Lollipop问题。但是alanv在另一篇帖子中有一行修复。它在API21中存在某种错误或疏忽。简单地说,只需将android:useLevel="true"
添加到您的圈子进度xml中。 Pedram的新方法仍然是正确的解决方案,但我只是认为我也分享了懒惰的解决方案。

https://github.com/passsy/android-HoloCircularProgressBar是执行此操作的库的一个示例。正如Tenfour04所说,它必须是有点自定义,因为这不是直接支持开箱即用的。如果此库不按您的意愿运行,您可以将其分叉并修改详细信息以使其按您的喜好工作。如果你实现其他人可以重用的东西,你甚至可以提交一个拉取请求来重新合并!

paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.STROKE);
canvas.drawCircle(150, 150, 140, paint);
paint.setColor(Color.parseColor("#FFDB4C"));
paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.FILL);
final RectF oval = new RectF();
paint.setStyle(Paint.Style.STROKE);
oval.set(10,10,290,290);
canvas.drawArc(oval, 270, ((i*360)/100), false, paint);
paint.setStrokeWidth(0);
paint.setTextAlign(Align.CENTER);
paint.setColor(Color.parseColor("#8E8E93"));
