1、先搞好一个等待框的布局：
<?xml version="1.0" encoding="utf-8"?> 这个布局是这样的：
2、然后开始自定义个DialogFragment了：
/** * 等待弹框 */public class LoadingDialog extends DialogFragment { private String msg = "正在加载"; private boolean onTouchOutside = true; private TextView textView; @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { Objects.requireNonNull(Objects.requireNonNull(getDialog()).getWindow()).setBackgroundDrawableResource(android.R.color.transparent); getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE); getDialog().setCanceledOnTouchOutside(onTouchOutside); View loadingView = inflater.inflate(R.layout.dialog_loading, container); textView= loadingView.findViewById(R.id.textView); textView.setText(msg); return loadingView; } public LoadingDialog setMsg(String msg) { this.msg = msg; if (textView!= null) { textView.setText(msg); } return this; } public LoadingDialog setOnTouchOutside(boolean onTouchOutside) { this.onTouchOutside = onTouchOutside; if(getDialog() != null){ getDialog().setCanceledOnTouchOutside(onTouchOutside); } return this; }}
3、使用：
private LoadingDialog loadingDialog;//显示等待框public void showLoading(String msg,boolean touch){ if(loadingDialog == null){ loadingDialog = new LoadingDialog(); }else{ loadingDialog.dismiss(); } loadingDialog.setMsg(msg) .setOnTouchOutside(touch) .show(getSupportFragmentManager(),"loading"); //fragment的话就把getSupportFragmentManager参数换成getChildFragmentManager}//动态修改等待框中的文字public void setLoadingMsg(String msg){ if(loadingDialog == null){ return; } loadingDialog.setMsg(msg);}//隐藏等待框public void hideLoading(){ if(loadingDialog != null){ loadingDialog.dismiss(); }}打完，收工！
