package com.actionbarsherlock.sample.demos;

import android.os.Bundle;
import android.os.Handler;
import android.view.View;

import com.actionbarsherlock.app.SherlockActivity;
import com.actionbarsherlock.view.Window;

public class Progress extends SherlockActivity  {
    Handler mHandler = new Handler();
    Runnable mProgressRunner = new Runnable() {
        @Override
        public void run() {
            mProgress += 2;

            int progress = (Window.PROGRESS_END - Window.PROGRESS_START) / 100 * mProgress;
            setSupportProgress(progress);

            if (mProgress < 100) {
                mHandler.postDelayed(mProgressRunner, 50);
            }
        }
    };

    private int mProgress = 100;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        setTheme(SampleList.THEME); //Used for theme switching in samples
        super.onCreate(savedInstanceState);

        //This has to be called before setContentView and you must use the
        //class in com.actionbarsherlock.view and NOT android.view
        requestWindowFeature(Window.FEATURE_PROGRESS);

        setContentView(R.layout.progress);

        findViewById(R.id.go).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                if (mProgress == 100) {
                    mProgress = 0;
                    mProgressRunner.run();
                }
            }
        });
    }
}



注意

requestWindowFeature(Window.FEATURE_PROGRESS);


这个Window是actionbarsherlock带的 不是系统的

计算进度

int progress = (Window.PROGRESS_END - Window.PROGRESS_START) / 100 * mProgress;
setSupportProgress(progress);


加载到100%后,进度条会有渐变消失的效果
