记录一个在项目中比较实用的进度条

1.初始化进度条

    protected Dialog loadingDialog = null;
     /*
    * 初始化
    * */
public static Dialog createProgressDialog(Context context, String hint) {

        LayoutInflater inflater = LayoutInflater.from(context);
        View view = inflater.inflate(R.layout.dialog_progress, null);
        TextView msgView = (TextView) view.findViewById(R.id.tv_msg);

        if (!TextUtils.isEmpty(hint)) {
            msgView.setVisibility(View.VISIBLE);
            msgView.setText(hint);
        }
//        else msgView.setVisibility(View.GONE);
        Dialog loading = new Dialog(context, R.style.CustomProgressDialog);
        WindowManager.LayoutParams lp = loading.getWindow().getAttributes();
        lp.gravity = Gravity.CENTER;
        loading.setContentView(view, lp);
        return loading;

    }

2.显示进度条


  /*
  * 显示进度条
  * strMsg 显示文本内容
  * */
public void showProgress(String strMsg) {
        if (null == loadingDialog) {
            loadingDialog = createProgressDialog(this, strMsg + "");
        }
        loadingDialog.show();
       /*下面两行代码点击进度条可以实现隐藏隐藏*/
        loadingDialog.setCancelable(true);
        loadingDialog.setCanceledOnTouchOutside(true);

        //  loadingDialog.setCancelable(false);//进度条不消失
    }

//--------------------------------------------------------

   /*
    * 显示进度条
    * */
public void showProgress() {

        if (null == loadingDialog) {
            loadingDialog = createProgressDialog(this, getString(R.string.loading_waiting));
        }
        loadingDialog.show();
        /*下面两行代码点击可以隐藏进度条*/
        loadingDialog.setCancelable(true);
        loadingDialog.setCanceledOnTouchOutside(true);
 //  loadingDialog.setCancelable(false);//进度条不消失
    }

3.隐藏进度条

 /*
 * 隐藏显示进度条
 * */
public void dismissProgress() {
        if ((loadingDialog != null) && (loadingDialog.isShowing()))
            loadingDialog.dismiss();
        loadingDialog = null;
    }

4.销毁进度条

   @Override
    protected void onDestroy() {
        super.onDestroy();
        if(loadingDialog!=null){
            loadingDialog.dismiss();
        }
    }
