自定義ProgressDialog

最近工作中需要用到progressDialog，可是系統自帶的黑色progressDialog又是其丑無比，無奈只能自己自定義了，在網上查看別人的例子，并自己整理了一份Demo：

先上圖：

MyProgressDialog：

package com.example.myprogressdialog_zzw;

import android.app.Dialog;
import android.content.Context;
import android.graphics.drawable.AnimationDrawable;
import android.view.Gravity;
import android.view.View;
import android.view.animation.Animation;
import android.widget.ImageView;
import android.widget.TextView;

/**

 */
public class MyProgressDialog extends Dialog
{
    private Context context;
    private static MyProgressDialog myProgressDialog = null;

    public MyProgressDialog(Context context)
    {
        super(context);
        this.context = context;
    }

    public MyProgressDialog(Context context, int theme)
    {
        super(context, theme);
    }

    public static MyProgressDialog createDialog(Context context)
    {
        myProgressDialog = new MyProgressDialog(context,
                R.style.myprogressDialog);
        myProgressDialog.setContentView(R.layout.dialog_layout);
        myProgressDialog.getWindow().getAttributes().gravity = Gravity.CENTER;
        return myProgressDialog;

    }

    /*
     * (non-Javadoc)
     *
     * @see android.app.Dialog#onWindowFocusChanged(boolean) 設置動畫
     */
    @Override
    public void onWindowFocusChanged(boolean hasFocus)
    {
        // TODO Auto-generated method stub
        super.onWindowFocusChanged(hasFocus);
        ImageView p_w_picpath_loadingp_w_picpath = (ImageView) myProgressDialog
                .findViewById(R.id.p_w_picpath_loadingp_w_picpath);
        AnimationDrawable animation = (AnimationDrawable) p_w_picpath_loadingp_w_picpath
                .getBackground();
        animation.start();
    }

    public MyProgressDialog setTitle(String strTitle)
    {
        return myProgressDialog;
    }

    /**
     * @param strMessage
     * @return 設置progressDialog的消息內容
     */
    public MyProgressDialog setMessage(String strMessage)
    {
        TextView tv_loadingmsg = (TextView) myProgressDialog
                .findViewById(R.id.tv_loadingmsg);
        if (tv_loadingmsg != null)
        {
            tv_loadingmsg.setText(strMessage);
        }
        return myProgressDialog;
    }
}

在MainActivity中對MyProgressDialog進行調用，為了模仿網絡訪問結束后，關閉ProgressDialog的過程，采用了線程的sleep，運行5秒后關閉ProgressDialog，上代碼：

package com.example.myprogressdialog_zzw;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

/**

 * 采用線程的的sleep模擬下載結束后關閉progressDialog
 *
 */
public class MainActivity extends Activity
{
    MyProgressDialog myProgressDialog = null;
    Handler handler = new Handler()
    {
        public void handleMessage(Message msg)
        {
            if (msg.what == 1)
            {
                Log.e("接收到消息", "" + msg.what);
                if (myProgressDialog != null)
                {
                    myProgressDialog.dismiss();
                    myProgressDialog = null;
                }
                Toast.makeText(MainActivity.this, "加載完成！", Toast.LENGTH_SHORT)
                        .show();
            }
        };
    };

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn_go = (Button) findViewById(R.id.button1);
        btn_go.setOnClickListener(new OnClickListener()
        {

            @Override
            public void onClick(View v)
            {
                if (myProgressDialog == null)
                {
                    myProgressDialog = MyProgressDialog
                            .createDialog(MainActivity.this);
                    myProgressDialog.setMessage("努力加載中...");

                }
                myProgressDialog.show();
                new Thread()
                {
                    @Override
                    public void run()
                    {
                        Log.e("線程", "進入線程！");
                        try
                        {
                            Thread.sleep(5000);
                            Message msg = new Message();
                            msg.what = 1;
                            handler.sendMessage(msg);
                        }
                        catch (InterruptedException e)
                        {
                            Log.e("異常", "失敗！異常");
                        }

                    }
                }.start();

            }
        });
    }

    @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;
    }

}
