import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.ProgressBar;

import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    private ProgressBar pbHorizontal;

    private Button button;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        //初始化控件

        pbHorizontal = findViewById(R.id.pbCircle);

        button = findViewById(R.id.button);

        //按钮监听器

        button.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                //setProgress()设置进度条进度，getProgress获取进度条进度

                pbHorizontal.setProgress(pbHorizontal.getProgress()+10);

            }

        });
