自定义底部弹出Dialog（老掉牙的需求还是记录一下吧）

（1）布局：

phonto_dialog.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
style="@style/choice_dialog1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/shape_win_photo_bg"
android:orientation="vertical"
android:padding="20dp" >

<Button
android:id="@+id/btn2"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="@drawable/selector_photo_bg"
android:gravity="center"
android:text="拍照"
android:textSize="15sp" />

<Button
android:id="@+id/btn1"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginTop="10dp"
android:background="@drawable/selector_photo_bg"
android:gravity="center"
android:text="从相册中选择"
android:textSize="15sp" />

<Button
android:id="@+id/btn_cancle_photo"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginTop="10dp"
android:background="@drawable/selector_photo_bg"
android:gravity="center"
android:text="取消"
android:textSize="15sp" />

</LinearLayout>

其中：

shape_win_photo_bg

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >

<corners
android:topLeftRadius="7dp"
android:topRightRadius="7dp" />

<solid android:color="#404848" />

</shape>

selector_photo_bg

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_pressed="true">
<shape android:shape="rectangle">
<corners android:radius="5dp" />
<solid android:color="#d81e06" />
</shape>
</item>

<item android:state_focused="true">
<shape android:shape="rectangle">
<corners android:radius="5dp" />
<solid android:color="#d81e06" />
</shape>
</item>

<item >
<shape android:shape="rectangle">
<corners android:radius="5dp" />
<solid android:color="#D0D0D0" />
</shape>
</item>
</selector>

java中调用

Dialog dialog = null;
public void selectImg(){

if(dialog != null && dialog.isShowing()){
dialog.dismiss();
return;
}
dialog = new Dialog(this);
Button select_poto_btn, camera_poto_btn,btn_cancle_photo;
View view = LayoutInflater.from(this).inflate(R.layout.phonto_dialog, null);
select_poto_btn = (Button) view.findViewById(R.id.btn1);
camera_poto_btn = (Button) view.findViewById(R.id.btn2);
btn_cancle_photo = (Button) view.findViewById(R.id.btn_cancle_photo);
select_poto_btn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
startImgIntent(SELECT_FROM_IMGS_REQUESTCODE);
dialog.dismiss();

}
});
camera_poto_btn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

startTakePhoto();
dialog.dismiss();
}
});

btn_cancle_photo.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
dialog.dismiss();
}
});

dialog.setContentView(view);
WindowManager.LayoutParams attributes = dialog.getWindow().getAttributes();
attributes.width = WindowManager.LayoutParams.MATCH_PARENT;
attributes.height = WindowManager.LayoutParams.WRAP_CONTENT;
attributes.gravity = Gravity.BOTTOM;
attributes.windowAnimations = R.style.mydialogstyle;
dialog.getWindow().setAttributes(attributes);
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
dialog.show();
}

其中：

mydialogstyle

<style name="mydialogstyle" >
<item name="@android:windowEnterAnimation">@anim/push_bottom_in</item>
<item name="@android:windowExitAnimation">@anim/push_bottom_out</item>
</style>

其中push_bottom_in

<?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="500"
android:fromYDelta="100%p"
android:toYDelta="0"
/>
</set>

push_bottom_out

<?xml version="1.0" encoding="utf-8"?>
<!-- 上下滑出式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
android:duration="500"
android:fromYDelta="0"
android:toYDelta="100%p" />
</set>
