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);
	}

@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);

}

使用getDialog的方法

	@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;
	}

@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;

}

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;
	}

}

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;

}
