首先看下效果图，确保是你想要的效果：



xml文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="@drawable/pop_bg"
android:orientation="vertical" >

<TextView
android:id="@+id/title"
android:layout_width="fill_parent"
android:layout_height="40.0dip"
android:layout_marginTop="15dp"
android:gravity="center"
android:text="设置号码"
android:textColor="#fffffb"
android:textSize="20sp"
android:visibility="visible" />

<!--   <LinearLayout
android:id="@+id/contentView"
android:layout_width="fill_parent"
android:layout_height="wrap_content" > -->

<EditText
android:id="@+id/number"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="5dp"
android:gravity="left|center"
android:hint="号码" />
<!-- </LinearLayout> -->

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="60.0dip"
android:layout_gravity="bottom"
android:layout_marginTop="5dp"
android:gravity="center"
android:orientation="horizontal" >

<Button
android:id="@+id/positiveButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/btn_ok_selector"
android:gravity="center" />

<Button
android:id="@+id/negativeButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20.0dip"
android:background="@drawable/btn_cancel_selector"
android:gravity="center" />
</LinearLayout>

</LinearLayout>

style样式：

<style name="mydialogstyle" parent="android:style/Theme.Dialog">

        <item name="android:windowNoTitle">true</item>

    </style>

java代码

import android.app.Dialog;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
/**
* @Function: 自定义对话框

*/
public class CustomDialog extends Dialog {
private EditText editText;
private Button positiveButton, negativeButton;
private TextView title;

public CustomDialog(Context context) {
super(context,R.style.CustomDialog);
setCustomDialog();
}

private void setCustomDialog() {
View mView = LayoutInflater.from(getContext()).inflate(R.layout.dialog_normal_layout, null);
title = (TextView) mView.findViewById(R.id.title);
editText = (EditText) mView.findViewById(R.id.number);
positiveButton = (Button) mView.findViewById(R.id.positiveButton);
negativeButton = (Button) mView.findViewById(R.id.negativeButton);
super.setContentView(mView);
}

public View getEditText(){
return editText;
}

@Override
public void setContentView(int layoutResID) {
}

@Override
public void setContentView(View view, LayoutParams params) {
}

@Override
public void setContentView(View view) {
}

/**
* 确定键监听器
* @param listener
*/
public void setOnPositiveListener(View.OnClickListener listener){
positiveButton.setOnClickListener(listener);
}
/**
* 取消键监听器
* @param listener
*/
public void setOnNegativeListener(View.OnClickListener listener){
negativeButton.setOnClickListener(listener);
}
}

使用方法：

// 弹窗
private void dialog() {
dialog = new CustomDialog(WorkspaceActivity.this);
EditText editText = (EditText) dialog.getEditText();//方法在CustomDialog中实现
dialog.setOnPositiveListener(new OnClickListener() {
@Override
public void onClick(View v) {
//dosomething youself
dialog2.dismiss();
}
});
dialog.setOnNegativeListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog2.dismiss();
}
});
dialog.show();
}
