由 主宰稳场 提交于 2019-12-07 04:03:57
问题 I' using ProgressDialog to show the user that he has to wait and to make the surface of my app "untouchable" while the user has to wait. I added a Button to the progressDialog which should start some actions if certain conditions are true. The problem is that everytime the user press the button the progressDialog gets automatically dismissed. Even if no action is triggered. How can I prevent the progressDialog from getting dismissed when onClick is called? thx & regards EDIT: connectingDialog

Android ProgressDialog使用总结

由 孤街醉人 提交于 2019-12-06 22:30:33
ProgressDialog的使用 ProgressDialog 继承自AlertDialog，AlertDialog继承自Dialog,实现DialogInterface接口。 ProgressDialog的创建方式有两种，一种是new Dialog ,一种是调用Dialog的静态方法Dialog.show()。 // 方式一：new Dialog final ProgressDialog dialog = new ProgressDialog(this); dialog.show(); // 方式二：使用静态方式创建并显示，这种进度条只能是圆形条,设置title和Message提示内容 ProgressDialog dialog2 = ProgressDialog.show(this, "提示", "正在登陆中"); // 方式三 使用静态方式创建并显示，这种进度条只能是圆形条,这里最后一个参数boolean indeterminate设置是否是不明确的状态 ProgressDialog dialog3 = ProgressDialog .show(this, "提示", "正在登陆中", false); // 方式四 使用静态方式创建并显示，这种进度条只能是圆形条,这里最后一个参数boolean cancelable 设置是否进度条是可以取消的 ProgressDialog
