自定义对话框中的java.lang.IllegalStateException [英] java.lang.IllegalStateException in Custom Dialog
问题描述
我是Android新手，正在使用自定义警报对话框
I am new to Android and I'm working on custom alert dialog
我想在单击编辑按钮时打开另一个对话框，并且代码在下面
I want to open a another dialog-box on click of edit button and code is below
if (v.getId() == R.id.edt_order) {
System.out.println(" edit buton click");
System.out.println("Click my Order");
System.out.println(" edit clickkkkkkkkkkkkkk");
LayoutInflater li = LayoutInflater.from(getApplicationContext());
View promptsView = li.inflate(R.layout.prompts, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
getApplicationContext());
// set prompts.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editTextDialogUserInput);
// set dialog message
alertDialogBuilder
.setCancelable(false)
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// get user input and set it to result
// edit text
// result.setText(userInput.getText());
System.out.println("Click ok");
// insertData(userInput.getText().toString().trim());
Toast.makeText(getApplicationContext(), "Category added", 5000).show();
// loadSpinnerData();
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
dialog.cancel();
}
});
// create alert dialog
alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
但是我遇到了一个例外，我的log cat输出如下所示
But I am getting an exception and my log cat output is as follow

即使我的红十字按钮工作正常，我也使用相同的代码多次用TextView显示AlertDialog，但我没有得到什么结果代码错误。任何帮助都非常感谢。
Even my redcross button is working fine and I've used same code for showing AlertDialog with TextView many times, but I did not get what is going wrong with code. Any help is really appreciated. Thanks in advance.
现在我得到了我想要的东西，但是编辑和保存两者都重叠在一起。我想隐藏编辑（蓝色按钮）并清楚地显示保存按钮。
Now i got whatever i want , but edit and save both are coming both with overlap . I want to hide edit ( blue button )and make visible save button clearly.
推荐答案
如果您阅读了 getApplicationContext（）会发现，只有在需要生命周期与当前上下文分开的 Context 时，才应使用此选项。这不适用于您的示例并将此对象用作className类型的对象。我认为在这里您可以使用
If you read the documentation at getApplicationContext() you find that you should only use this if you need a Context whose lifecycle is separate from the current context. This doesn't apply in your examples and use of this object as an object of type className.I think here you can use
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
OR
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(ClassNAme.this);
两者都应该起作用。
