一、先上效果图
二、自定义dialog类
package com.wwy.customdialog_demo;
import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.util.TypedValue;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;
/**
* created by summer at 2017/02/01
*/
public class CustomDialog extends Dialog {
public CustomDialog(Context context) {
super(context);
}
public CustomDialog(Context context, int theme) {
super(context, theme);
}
public static class Builder {
private Context context;
private String title;
private String message;
private String positiveButtonText;
private String negativeButtonText;
private View contentView;
private DialogInterface.OnClickListener positiveButtonClickListener;
private DialogInterface.OnClickListener negativeButtonClickListener;
public Builder(Context context) {
this.context = context;
}
public Builder setMessage(String message) {
this.message = message;
return this;
}
/**
* Set the Dialog message from resource
*
* @param
* @return
*/
public Builder setMessage(int message) {
this.message = (String) context.getText(message);
return this;
}
/**
* Set the Dialog title from resource
*
* @param title
* @return
*/
public Builder setTitle(int title) {
this.title = (String) context.getText(title);
return this;
}
/**
* Set the Dialog title from String
*
* @param title
* @return
*/
public Builder setTitle(String title) {
this.title = title;
return this;
}
public Builder setContentView(View v) {
this.contentView = v;
return this;
}
/**
* Set the positive button resource and it's listener
*
* @param positiveButtonText
* @return
*/
public Builder setPositiveButton(int positiveButtonText,
DialogInterface.OnClickListener listener) {
this.positiveButtonText = (String) context
.getText(positiveButtonText);
this.positiveButtonClickListener = listener;
return this;
}
public Builder setPositiveButton(String positiveButtonText,
DialogInterface.OnClickListener listener) {
this.positiveButtonText = positiveButtonText;
this.positiveButtonClickListener = listener;
return this;
}
public Builder setNegativeButton(int negativeButtonText,
DialogInterface.OnClickListener listener) {
this.negativeButtonText = (String) context
.getText(negativeButtonText);
this.negativeButtonClickListener = listener;
return this;
}
public Builder setNegativeButton(String negativeButtonText,
DialogInterface.OnClickListener listener) {
this.negativeButtonText = negativeButtonText;
this.negativeButtonClickListener = listener;
return this;
}
public CustomDialog create() {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// instantiate the dialog with the custom Theme
final CustomDialog dialog = new CustomDialog(context,R.style.CustomDialog);
View layout = inflater.inflate(R.layout.layout_dialog, null);
dialog.addContentView(layout, new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT));
// set the dialog title
((TextView) layout.findViewById(R.id.dialog_title)).setText(title);
//设置在窗口中的大小位置
Window dialogWindow = dialog.getWindow();
WindowManager.LayoutParams lp = dialogWindow.getAttributes();
lp.height = dp2px(context,360); // 高度
lp.width = dp2px(context,275);
dialogWindow.setAttributes(lp);
if (positiveButtonText != null) {
((Button) layout.findViewById(R.id.btn_dialog_ok))
.setText(positiveButtonText);
if (positiveButtonClickListener != null) {
((Button) layout.findViewById(R.id.btn_dialog_ok))
.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
positiveButtonClickListener.onClick(dialog,
DialogInterface.BUTTON_POSITIVE);
}
});
}
} else {
// if no confirm button just set the visibility to GONE
layout.findViewById(R.id.btn_dialog_ok).setVisibility(
View.GONE);
}
// set the cancel button
if (negativeButtonText != null) {
((Button) layout.findViewById(R.id.btn_dialog_cancel))
.setText(negativeButtonText);
if (negativeButtonClickListener != null) {
((Button) layout.findViewById(R.id.btn_dialog_cancel))
.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
negativeButtonClickListener.onClick(dialog,
DialogInterface.BUTTON_NEGATIVE);
}
});
}
} else {
// if no confirm button just set the visibility to GONE
layout.findViewById(R.id.btn_dialog_cancel).setVisibility(
View.GONE);
}
// set the content message
if (message != null) {
((TextView) layout.findViewById(R.id.dialog_message)).setText(message);
} else if (contentView != null) {
// if no message set
// add the contentView to the dialog body
((LinearLayout) layout.findViewById(R.id.dialog_content))
.removeAllViews();
((LinearLayout) layout.findViewById(R.id.dialog_content)).addView(
contentView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
}
dialog.setContentView(layout);
return dialog;
}
}
/**
* dp转px
*
* @param context
* @return
*/
public static int dp2px(Context context, float dpVal) {
return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
dpVal, context.getResources().getDisplayMetrics());
}
}
三、dialog的style放到values/styles.xml路径下
<!--自定义弹框-->
<style name="CustomDialog" parent="android:style/Theme.Dialog">
<!--背景颜色及和透明程度-->
<item name="android:windowBackground">@android:color/transparent</item>
<!--是否去除标题 -->
<item name="android:windowNoTitle">true</item>
<!--是否去除边框-->
<item name="android:windowFrame">@null</item>
<!--是否浮现在activity之上-->
<item name="android:windowIsFloating">true</item>
<!--是否模糊-->
<item name="android:backgroundDimEnabled">true</item>
</style>
四、dialog的layout布局实现(自定义尺寸和背景图片)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="225dp"
android:layout_height="360dp"
android:background="@drawable/newyear_background"
android:orientation="vertical">
<TextView
android:visibility="invisible"
android:id="@+id/dialog_title"
android:layout_width="match_parent"
android:layout_height="40dp"
android:gravity="center"
android:paddingBottom="4dp"
android:paddingTop="4dp"
android:text=""
android:textColor="#000000"
android:textSize="20sp" />
<LinearLayout
android:id="@+id/dialog_content"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:gravity="center">
<TextView
android:id="@+id/dialog_message"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:text=" 恭祝大家新年快乐,万事如意,身体健康,新的一年里开心每一天!"
android:lineSpacingExtra="6dp"
android:textColor="#111111"
android:textStyle="bold"
android:textSize="22sp" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="30dp"
android:layout_margin="10dp"
android:layout_alignParentBottom="true"
android:orientation="horizontal">
<Button
android:id="@+id/btn_dialog_cancel"
android:textColor="#888888"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_weight="1"
android:text="取消"
android:background="#00000000"
android:textAllCaps="false"
android:textSize="18sp" />
<Button
android:id="@+id/btn_dialog_ok"
android:textColor="#1885ff"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_weight="1"
android:text="确定"
android:background="#00000000"
android:textAllCaps="false"
android:textSize="18sp" />
</LinearLayout>
</RelativeLayout>
五、调用弹框和确定、取消按钮事件(此例子中我为了方便,直接指定Button的onClick的属性调用点击事件)
/**
* 自定义弹框
*/
public void showDialog(View v) {
CustomDialog.Builder builder = new CustomDialog.Builder(this);
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//唤醒沃掌控进行认证
Toast.makeText(MainActivity.this, "新年快乐弹框", Toast.LENGTH_LONG).show();
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
//直接关闭
// finish();
}
});
builder.create().show();
}
六、demo中用到的newyear_dialog.png背景图
