The LoadingActivity.java:
package com.apps.yourappname;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
public class LoadingActivity extends AppCompatActivity {
private ProgressDialog mProgressDialog;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.loading_activity);
}
public void spinProgressDialog(View v) {
mProgressDialog = new ProgressDialog(LoadingActivity.this);
mProgressDialog.setMessage("Simple Spin Progress Dialog");
doProgress();
}
public void barProgressDialog(View v) {
mProgressDialog = new ProgressDialog(LoadingActivity.this);
mProgressDialog.setMessage("Simple Bar Progress Dialog");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setMax(100);
doProgress();
}
public void fancyBarProgressDialog(View v) {
mProgressDialog = new ProgressDialog(LoadingActivity.this);
mProgressDialog.setMessage("Fancy Bar Progress Dialog");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setProgressDrawable(getResources().getDrawable(R.drawable.fancy_progress_bar));
mProgressDialog.setMax(100);
doProgress();
}
void doProgress() {
mProgressDialog.show();
new Thread(){
@Override
public void run() {
while(mProgressDialog.getProgress()<mProgressDialog.getMax()) {
try{
Thread.sleep(300);
}catch (InterruptedException e) {
e.printStackTrace();
}
handler.sendMessage(handler.obtainMessage());
if(mProgressDialog.getProgress()>=mProgressDialog.getMax()) {
mProgressDialog.dismiss();
}
}
}
}.start();
}
Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
mProgressDialog.incrementProgressBy(1);
}
};
}
