I want to have a simple gauge view where i will define the start value and the end value and have a pointer to show given variable value.
Another one i found at Evelina Vrabie's blog, used it and worked perfect!
Look at Evelina Vrabie's GitHub. It has a gauge library and some samples to interact with.
Big thanks to the owner Evelina Vrabie!
However it is not working on XHDPI/Few versions of android devices (above 4). Problem is the text in gauge view.
I made this one a while ago. Feel free to clone and modify. (It takes some ideas from the old Vintage Thermometer.)
github.com/Pygmalion69/Gauge
It can easily be added to your Gradle project:
repositories {
maven {
url 'https://www.jitpack.io'
}
}
dependencies {
compile 'com.github.Pygmalion69:Gauge:1.1'
}
The views are declared in XML:
<de.nitri.gauge.Gauge
android:id="@+id/gauge1"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_gravity="center"
android:layout_marginTop="10dp"
android:layout_weight="0.75"
gauge:labelTextSize="42"
gauge:maxValue="1000"
gauge:minValue="0"
gauge:totalNicks="120"
gauge:valuePerNick="10"
gauge:upperText="Qty"
gauge:lowerText="@string/per_minute" />
Here's an example of setting the values programmatically:
final Gauge gauge1 = (Gauge) findViewById(R.id.gauge1);
final Gauge gauge2 = (Gauge) findViewById(R.id.gauge2);
final Gauge gauge3 = (Gauge) findViewById(R.id.gauge3);
final Gauge gauge4 = (Gauge) findViewById(R.id.gauge4);
gauge1.moveToValue(800);
HandlerThread thread = new HandlerThread("GaugeDemoThread");
thread.start();
Handler handler = new Handler(thread.getLooper());
handler.postDelayed(new Runnable() {
@Override
public void run() {
gauge1.moveToValue(300);
}
}, 2800);
handler.postDelayed(new Runnable() {
@Override
public void run() {
gauge1.moveToValue(550);
}
}, 5600);
HandlerThread gauge3Thread = new HandlerThread("Gauge3DemoThread");
gauge3Thread.start();
Handler gauge3Handler = new Handler(gauge3Thread.getLooper());
gauge3Handler.post(new Runnable() {
@Override
public void run() {
for (float x = 0; x <= 6; x += .1) {
float value = (float) Math.atan(x) * 20;
gauge3.moveToValue(value);
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
});
gauge4.setValue(333);
All other gauges you recommended have bugs and don't run fine on Kitkat and Lollipop. Also there is no Android Studio and gradle friendly library here.
Here's git repo for the more recent one updated for Lollipop you can use with Gradle:
After you include library in your project add gaugelibrary to xml layout of your activity:
<io.sule.gaugelibrary.GaugeView
android:id="@+id/gauge_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
gauge:showOuterShadow="false"
gauge:showOuterRim="false"
gauge:showInnerRim="false"
gauge:needleWidth="0.010"
gauge:needleHeight="0.40"
gauge:scaleStartValue="0"
gauge:scaleEndValue="100"
/>
This will show static gauge without needle. To instantiate needle with random animation you need to do that in activity class file. See how it's done here:
package io.sule.testapplication;
import android.app.Activity;
import android.os.Bundle;
import android.os.CountDownTimer;
import android.view.Menu;
import android.view.MenuItem;
import java.util.Random;
import io.sule.gaugelibrary.GaugeView;
public class MainActivity extends Activity {
private GaugeView mGaugeView;
private final Random RAND = new Random();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mGaugeView = (GaugeView) findViewById(R.id.gauge_view);
mTimer.start();
}
private final CountDownTimer mTimer = new CountDownTimer(30000, 1000) {
@Override
public void onTick(final long millisUntilFinished) {
mGaugeView.setTargetValue(RAND.nextInt(101));
}
@Override
public void onFinish() {}
};
}
This will instantiate needle and make it animate moving to random values.
On this site you will find some free customizable gauges.
ScComponents
Very easy to install and well documented. For example you can have for free something like this in 5 minutes following the instruction below.
Go on the above linked website. Click the GR004 and after the popup appear click on "Download for FREE". The library will downloaded, unzip and follow the instruction to install the library (aar file) inside your Android project.
Write this code in your XML layout and your gauge will done:
<com.sccomponents.gauges.gr004.GR004
android:layout_width="match_parent"
android:layout_height="match_parent" />
You have many XML options to customize it:
And the related function by coding.
Use this : Sample Project
It can easily be added to your Gradle project:
repositories {
maven {
url 'https://www.jitpack.io'
}
}
dependencies {
implementation 'com.jignesh13.speedometer:speedometer:1.0.0'
}
The views are declared in XML:
<com.jignesh13.speedometer.SpeedoMeterView
android:id="@+id/speedometerview"
android:layout_width="250dp"
android:layout_height="250dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.453"
app:layout_constraintStart_toStartOf="parent"
app:backimage="@android:color/black"
app:needlecolor="#fff"
app:removeborder="false"
app:linecolor="#fff"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.079" />
I don't know whether the late answer is going to help or not. I also came to the same situation where i want to use a gauge to visualize data, since gauge is not given as widget in android, as a enthusiast i went for libraries like above which can be found through various links in the Internet, although it was quite helpful(thanks to the wonderful authors of it..) i find myself difficult to visualize the during certain situations, so another solution what i have done is for my app is i integreated the JavaScript gauges into my android application. You can do that by the following steps
This is sample code for viewing the webview content..
web = (WebView) findViewById(R.id.webview01); progressBar = (ProgressBar) findViewById(R.id.progressBar1);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
web.post(new Runnable() {
@Override
public void run() {
web.loadUrl("file:///android_asset/fonts/guage.html");
}
});
The above for loading the html & javscript.
public class myWebClient extends WebViewClient
{
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
progressBar.setVisibility(View.VISIBLE);
view.loadUrl(url);
return true;
}
@Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
}
This the webview class
Kindly read through all, corrections are welcomed..!!
