1,定义Dialog

View view = inflater.inflate(R.layout.phone_dialog, null);
final Dialog builder = new Dialog(this, R.style.ActionSheetDialogStyle);
builder.setCanceledOnTouchOutside(true);
builder.setContentView(view);

--- 设置dialog占满屏幕

Window dialogWindow = dialog.getWindow();
WindowManager.LayoutParams lp = dialogWindow.getAttributes();
dialogWindow.setGravity(Gravity.CENTER);
lp.width = LayoutParams.FILL_PARENT;
dialogWindow.setAttributes(lp);

--
builder.show();

R.style.ActionSheetDialogStyle :

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

<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowContentOverlay">@null</item>

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

<item name="android:windowFrame">@null</item>

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

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

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

<item name="android:windowAnimationStyle">@style/ActionSheetDialogAnimation</item>
</style>

--------------------------

ActionSheetDialogAnimation:

---------------------------

@anim/actionsheet_dialog_in:

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="200"
android:fromYDelta="100%"
android:toYDelta="0" />

@anim/actionsheet_dialog_out

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="200"
android:fromYDelta="0"
android:toYDelta="100%" />

-----------------------------

ActionSheetDialog actionSheetDialog = new ActionSheetDialog(CreateActivitiesActivity.this);

actionSheetDialog.builder();
actionSheetDialog.setCancelable(true);
actionSheetDialog.setCanceledOnTouchOutside(true);
actionSheetDialog.addSheetItem("讲座", SheetItemColor.Blue,
new OnSheetItemClickListener() {
@Override
public void onClick(int which) {
tv_activityType.setText("讲座");
}
});

actionSheetDialog.addSheetItem("聚会", SheetItemColor.Blue,
new OnSheetItemClickListener() {
@Override
public void onClick(int which) {
tv_activityType.setText("聚会");
}
});

actionSheetDialog.addSheetItem("亲子游", SheetItemColor.Blue,
new OnSheetItemClickListener() {
@Override
public void onClick(int which) {
tv_activityType.setText("亲子游");
}
});
actionSheetDialog.show();
