public class MyDialog extends Dialog implements android.view.View.OnClickListener{
private Button cancel;
Context context;
View localView;
private RelativeLayout clearallpan;
protected MyDialog(Context context) {
super(context);
this.context = context;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
// 这句代码换掉dialog默认背景，否则dialog的边缘发虚透明而且很宽
// 总之达不到想要的效果
getWindow().setBackgroundDrawableResource(android.R.color.transparent);
LayoutInflater inflater = ((AnimationActivity) context).getLayoutInflater();
localView = inflater.inflate(R.layout.animclearpan, null);
localView.setAnimation(AnimationUtils.loadAnimation(context, R.anim.slide_bottom_to_top));
setContentView(localView);
// 这句话起全屏的作用
getWindow().setLayout(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);
initView();
initListener();
}
@Override
public boolean onTouchEvent(MotionEvent event) {
this.dismiss();
return super.onTouchEvent(event);
}
private void initListener() {
cancel.setOnClickListener(this);
clearallpan.setOnClickListener(this);
}
private void initView() {
cancel = (Button) findViewById(R.id.cancel);
clearallpan = (RelativeLayout) findViewById(R.id.clearallpan);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.cancel:
this.dismiss();
break;
case R.id.clearallpan:
Toast.makeText(context, "请在该区域之外点击", 0).show();
break;
}
}
}
animclearpan.xml布局文件如下：
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <!-- android:background="@drawable/clearpanbackground" --> <RelativeLayout android:id="@+id/clearallpan" android:layout_width="fill_parent" android:layout_height="300dp" android:layout_alignParentBottom="true" android:background="@android:color/white" > <Button android:id="@+id/clearall" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginLeft="10dip" android:layout_marginRight="10dip" android:layout_marginTop="20dip" android:layout_marginBottom="10dip" android:text="删除所有" android:textColor="#FFFFFFFF"/> <Button android:id="@+id/cancel" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginLeft="10dip" android:layout_marginRight="10dip" android:layout_marginTop="10dip" android:layout_marginBottom="20dip" android:text="取消" android:layout_below="@id/clearall" android:textColor="#FFFFFFFF"/> </RelativeLayout> </RelativeLayout>
动画效果slide_bottom_to_top.xml文件如下:
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator" > <translate android:duration="300" android:fromYDelta="100.0%" android:toYDelta="10.000002%" /> <alpha android:duration="50" android:fromAlpha="0.0" android:toAlpha="1.0" /> </set>
自定义Dialog,然后设置为透明背景，然后在View上面设置动画
2： 我们也可以把Acitivity变成Dialog样式,但是这样有个缺点:就是不同的手机room对activity中的跳转样式有所变化,当我设置Activity退出的动画时,没有效果。所以如果需求要求全屏的类似Dialog的样式，就自定义Dialog显示，不要把Activity转成Dialog样式.
一下是把Activity变成Dialog样式
1）Activity如下：
package com.example.picpopupwindow;
import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.Toast;
public class SelectPicPopupWindow extends Activity implements OnClickListener{
private Button btn_take_photo, btn_pick_photo, btn_cancel;
private LinearLayout layout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.alert_dialog);
btn_take_photo = (Button) this.findViewById(R.id.btn_take_photo);
btn_pick_photo = (Button) this.findViewById(R.id.btn_pick_photo);
btn_cancel = (Button) this.findViewById(R.id.btn_cancel);
layout=(LinearLayout)findViewById(R.id.pop_layout);
//添加选择窗口范围监听可以优先获取触点，即不再执行onTouchEvent()函数，点击其他地方时执行onTouchEvent()函数销毁Activity
layout.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "提示：点击窗口外部关闭窗口！",
Toast.LENGTH_SHORT).show();
}
});
//添加按钮监听
btn_cancel.setOnClickListener(this);
btn_pick_photo.setOnClickListener(this);
btn_take_photo.setOnClickListener(this);
}
//实现onTouchEvent触屏函数但点击屏幕时销毁本Activity
@Override
public boolean onTouchEvent(MotionEvent event){
finish();
return true;
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_take_photo:
break;
case R.id.btn_pick_photo:
break;
case R.id.btn_cancel:
break;
default:
break;
}
finish();
}
}
样式alert_dialog.xml如下
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center_horizontal" android:orientation="vertical" > <LinearLayout android:id="@+id/pop_layout" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center_horizontal" android:orientation="vertical" android:layout_alignParentBottom="true" android:background="@drawable/btn_style_alert_dialog_background" > <Button android:id="@+id/btn_take_photo" android:layout_marginLeft="20dip" android:layout_marginRight="20dip" android:layout_marginTop="20dip" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="拍照" android:background="@drawable/btn_style_alert_dialog_button" android:textStyle="bold" /> <Button android:id="@+id/btn_pick_photo" android:layout_marginLeft="20dip" android:layout_marginRight="20dip" android:layout_marginTop="5dip" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="从相册选择" android:background="@drawable/btn_style_alert_dialog_button" android:textStyle="bold" /> <Button android:id="@+id/btn_cancel" android:layout_marginLeft="20dip" android:layout_marginRight="20dip" android:layout_marginTop="15dip" android:layout_marginBottom="15dip" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="取消" android:background="@drawable/btn_style_alert_dialog_cancel" android:textColor="#ffffff" android:textStyle="bold" /> </LinearLayout> </RelativeLayout>
在清单文件中配置该Activity
<activity android:name=".SelectPicPopupWindow" android:theme="@style/MyDialogStyleBottom" /> <activity
MyDialogStyleBottom样式如下：
<style name="AnimBottom" parent="@android:style/Animation"> <item name="android:windowEnterAnimation">@anim/push_bottom_in</item> <!-- <item name="android:windowExitAnimation">@anim/push_bottom_out</item> --> </style> <style name="MyDialogStyleBottom" parent="android:Theme.Dialog"> <item name="android:windowAnimationStyle">@style/AnimBottom</item> <item name="android:windowFrame">@null</item> <!-- 边框 --> <item name="android:windowIsFloating">true</item> <!-- 是否浮现在activity之上 --> <item name="android:windowIsTranslucent">true</item> <!-- 半透明 --> <item name="android:windowNoTitle">true</item> <!-- 无标题 --> <item name="android:windowBackground">@android:color/transparent</item> <!-- 背景透明 --> <item name="android:backgroundDimEnabled">true</item> <!-- 模糊 --> </style>
动画push_bottom_in.xml如下：
<?xml version="1.0" encoding="utf-8"?> <!-- 上下滑入式 --> <set xmlns:android="http://schemas.android.com/apk/res/android" > <translate android:duration="200" android:fromYDelta="100%p" android:toYDelta="0" /> </set>
【Android】Dialog从下往上弹起(Dialog全屏，模态显示)
