其他注意事项：
1、如何设置自己的Dialogfragment没有标题栏？
可以通过两种方法来设置 ，一种是使用dialogfragment的setStyle函数，另外就是使用getDialog().getWindow().requestFeature方法，具体代码如下
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
//如果要使用此方法，则必须将代码放到onCreateDialog中，因为一旦其中的dialog创建成功后，setStyle将不再起作用
setStyle(STYLE_NO_TITLE, 0);
return super.onCreateDialog(savedInstanceState);
}

setStyle(STYLE_NO_TITLE,0);
returnsuper.onCreateDialog(savedInstanceState);
}
使用getDialog的方法
Java
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
dlgView = inflater.inflate(R.layout.add_customer_activiey, container);
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return dlgView;
}

BundlesavedInstanceState){
dlgView=inflater.inflate(R.layout.add_customer_activiey,container);
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
returndlgView;
}
2. The method show(FragmentManager, String) in the type DialogFragment is not applicable for the arguments (FragmentManager, String)
此问题常是由于你所自定义的DialogFragment子类继承自android.app.dialogfragment，而非继承自android.support.v4.app.DialogFragment，解决办法就是将你的自定义的DialogFragment子类继承自android.support.v4.app.DialogFragment。如下所示：
package com.bcoder.demos;
import android.annotation.SuppressLint;
import android.support.v4.app.DialogFragment; //import这个类
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
@SuppressLint("NewApi")
public class AddSubClassDialog extends DialogFragment {
View addview = null;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
addview = inflater.inflate(R.layout.add_sub_class, container);
return addview;
}
}
