ProgressDialog帶進度的Dialog

圓圈的進度條式 窗口直接用show，水平進度必須創建類並創建構造方法

 

 

圓圈的進度條式   的Dialog（窗口）
 public void showPD(View view) throws InterruptedException {
        final ProgressDialog dialog = ProgressDialog.show(this,"數據加載","數據加載中...");
       new Thread(new Runnable() {
           @Override
           public void run() {
               for (int i = 0;i<20;i++)
               {
                   try {
                       Thread.sleep(100);
                   } catch (InterruptedException e) {
                       e.printStackTrace();
                   }
               }
               dialog.dismiss();
               runOnUiThread(new Runnable() {
                   @Override
                   public void run() {
                       Toast.makeText(DialogActivity.this,"加載完成",Toast.LENGTH_SHORT).show();
                   }
               });
           }
       }).start();

    }

水平的進度條式   的Dialog（窗口）

public void showPD2(View view)
    {
        final ProgressDialog pd = new ProgressDialog(this);
        pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        pd.show();

        new Thread(new Runnable() {
            @Override
            public void run() {
                pd.setMax(20);
                for(int i =0;i<20;i++)
                {
                    try {
                        Thread.sleep(100);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    pd.setProgress(pd.getProgress()+1);

                }
                pd.dismiss();
            }
        }).start();
    }


一個show(ProgressDialog.show) 一個new (new ProgressDialog(this))
