android控件开发之progress

本博文主要讲述的是android开发中的progress进度条的使用方法，代码如下：

MainActivity.java：

package com.example.progress;

import android.os.Bundle;
import android.R.integer;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;

public class MainActivity extends Activity {

private ProgressBar firstBar = null;
private ProgressBar secendBar = null;
private Button myButton = null;
private int i = 0; //记录bar的位置

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

firstBar = (ProgressBar)findViewById(R.id.firstBar);
secendBar = (ProgressBar)findViewById(R.id.secendBar);
myButton = (Button)findViewById(R.id.myButton);

//绑定监听器
myButton.setOnClickListener(new myBuutonSetOnclickListener());

}

class myBuutonSetOnclickListener implements OnClickListener{

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(i == 0){
//设置progress bar可见
firstBar.setVisibility(View.VISIBLE);
secendBar.setVisibility(View.VISIBLE);

}
else if(i > 0 && i < firstBar.getMax()){
//设置进度条的主进度的当前值
firstBar.setProgress(i);
//设置进度条的第二进度的当前值
firstBar.setSecondaryProgress(i + 10);

}
else{
firstBar.setVisibility(View.GONE);
secendBar.setVisibility(View.GONE);
firstBar.setProgress(0);
firstBar.setSecondaryProgress(0);
i = -10;
}

i += 10;
}

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

}
