How to implement Linear ProgressBar in any android studio project
Progress bars are used to show progress of a task. For example, when you are uploading or downloading something from the internet, it is better to show the progress of download/upload to the user.
In android there is a class called ProgressDialog that allows you to create progress bar. In order to do this, you need to instantiate an object of this class. The code is below.
activity_main.xml
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="58dp"
android:text="Progress bar"
android:textColor="@android:color/holo_green_dark"
android:textSize="30dp"
android:textStyle="bold" />
android:id="@+id/button"
style="@style/Widget.AppCompat.Button.Borderless"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="@android:color/holo_blue_bright"
android:onClick="download"
android:text="Click Here" />
MainActivity.java
package com.friendvilla.simplecode;
import android.app.Activity;
import android.os.Bundle;
import android.app.ProgressDialog;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
Button b1;
private ProgressDialog progress;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b1 = (Button) findViewById(R.id.button);
}
public void download(View view){
progress=new ProgressDialog(this);
progress.setMessage("Progress Bar Start");
progress.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progress.setIndeterminate(true);
progress.setProgress(0);
progress.show();
final int totalProgressTime = 100;
final Thread t = new Thread() {
@Override
public void run() {
int jumpTime = 0;
while(jumpTime < totalProgressTime) {
try {
sleep(200);
jumpTime += 10;
progress.setProgress(jumpTime);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
t.start();
}
}
