Android调用自定义ProgressDialog-如何?
正在尝试创建自定义progressdialog,但不起作用 我的代码:Android调用自定义ProgressDialog-如何?,android,Android,正在尝试创建自定义progressdialog,但不起作用 我的代码: public class CustomProgressDialog extends ProgressDialog { public CustomProgressDialog(Context context) { super(context, R.style.progress_dialog); } public static CustomProgressDialog show(Context context
public class CustomProgressDialog extends ProgressDialog {
public CustomProgressDialog(Context context) {
super(context, R.style.progress_dialog);
}
public static CustomProgressDialog show(Context context, CharSequence title,
CharSequence message) {
return show(context, title, message, false);
}
public static CustomProgressDialog show(Context context, CharSequence title,
CharSequence message, boolean indeterminate) {
return show(context, title, message, indeterminate, false, null);
}
public static CustomProgressDialog show(Context context, CharSequence title,
CharSequence message, boolean indeterminate, boolean cancelable) {
return show(context, title, message, indeterminate, cancelable, null);
}
public static CustomProgressDialog show(Context context, CharSequence title,
CharSequence message, boolean indeterminate,
boolean cancelable, OnCancelListener cancelListener) {
CustomProgressDialog dialog = new CustomProgressDialog(context);
dialog.setTitle(title);
dialog.setCancelable(cancelable);
dialog.setOnCancelListener(cancelListener);
dialog.addContentView(new ProgressBar(context), new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
dialog.show();
return dialog;
}
}
我想如何称呼:
public static CustomProgressDialog dialog;
public static void showLoaderDialog(String sHead, String sMess) {
dialog=new CustomProgressDialog(mycontext).show(mycontext, sHead, sMess, true, true);
}
public static void hideLoaderDialog() {
dialog.dismiss();
}
但我只得到了crash:(为什么?如何调用此自定义对话框

也许,您应该这样调用dialog:
public static void showLoaderDialog(String sHead, String sMess) {
dialog=new CustomProgressDialog(mycontext);
dialog.show(mycontext, sHead, sMess, true, true);
}
但我可能错了
无论如何,show,please,代码行指的是CustomProgressDialog。java:37show,please,错误日志。在最初的帖子中,Macarse从
dialog
,而不是ProgressDialog
,扩展了他的自定义对话框。也许这就是问题所在?@lacas你已经解决了这个问题。如果是,请告诉我你是如何解决的。
