Android最简单的LoadingDialog Android最简单的LoadingDialog

Activity的基类

public class BaseAcitivity extends Activity {private AlertDialog alertDialog; public void showLoadingDialog() { alertDialog = new AlertDialog.Builder(this).create(); alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable()); alertDialog.setCancelable(false); alertDialog.setOnKeyListener(new DialogInterface.OnKeyListener() { @Override public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_SEARCH || keyCode == KeyEvent.KEYCODE_BACK) return true; return false; } }); alertDialog.show(); alertDialog.setContentView(R.layout.loading_alert); alertDialog.setCanceledOnTouchOutside(false); }public void dismissLoadingDialog() { if (null != alertDialog && alertDialog.isShowing()) { alertDialog.dismiss(); } } }

Fragment的基类

public class BaseFragment extends Fragment { private AlertDialog alertDialog; public void showLoadingDialog() { alertDialog = new AlertDialog.Builder(getActivity()).create(); alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable()); alertDialog.setCancelable(false); alertDialog.setOnKeyListener(new DialogInterface.OnKeyListener() { @Override public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_SEARCH || keyCode == KeyEvent.KEYCODE_BACK) return true; return false; } }); alertDialog.show(); alertDialog.setContentView(R.layout.loading_alert); alertDialog.setCanceledOnTouchOutside(false); }public void dismissLoadingDialog() { if (null != alertDialog && alertDialog.isShowing()) { alertDialog.dismiss(); } } }

XML：loading_alert

在styles.xml中添加

false true

【Android最简单的LoadingDialog】代码已经全部贴完，只需要复制Activity，Fragment的基类。然后自己的去继承这些。
用showLoadingDialog()方法开启LoadingDialog
用dismissLoadingDialog()方法关闭LoadingDialog
可以在原有的基础上修改xml布局实现更漂亮的Loading
