Android ProgressDialog 简单实用

    ProgressDialog progressDialog;

    @SuppressLint("HandlerLeak")
    Handler handler1 = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            //webapi信息装载到控件
//doSomeThing().....
            progressDialog.dismiss();
        }
    };

    //读取仓库列表
    public void GetWarehouseAll() {
        progressDialog.show();
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
//访问webapi
                    String json = HttpWebapi.DoPost(AppConfig.getUrl()+"api/WMS_PPR/GetWarehouseAll", new ArrayList<NameValuePair>());
                    Message msg = Message.obtain();
                    msg.obj = json;
                    handler1.sendMessage(msg);
                } catch (Exception e) {
                    progressDialog.dismiss();
                    e.printStackTrace();
                    Looper.prepare();
                    Toast.makeText(OutboundPOActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();
                    Looper.loop();
                }

            }
        }).start();
    }
    //endregion

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

        progressDialog=new ProgressDialog(MainActivity.this);

        //读取仓库列表
        GetWarehouseAll();

    }

1 在onCreate中初始化 ProgressDialog。

2 在调用方法GetWarehouseAll();中progressDialog.show(); 开启

3 在handleMessage中progressDialog.dismiss();停止

简单用法：

ProgressDialog pd = new ProgressDialog(this);
        pd.setTitle("提醒");
        pd.setMessage("正在加载中......");
        pd.show();
