dialog从底部弹出可修改

dialog从底部弹出可修改

1、代码

mPickerDialog = new Dialog(mContext, R.style.date_picker_dialog);
        mPickerDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        mPickerDialog.setContentView(R.layout.dialog_date_picker3);

        //背景透明
        mPickerDialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);

        Window window = mPickerDialog.getWindow();
        if (window != null) {
            //弹框从底部弹出
            window.setWindowAnimations(R.style.date_picker_dialog_anim);
            WindowManager.LayoutParams lp = window.getAttributes();
            lp.gravity = Gravity.BOTTOM;
            lp.width = WindowManager.LayoutParams.MATCH_PARENT;
            lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
            window.setAttributes(lp);
        }

2、style代码

<style name="date_picker_dialog_anim">
        <item name="android:windowEnterAnimation">@anim/dialog_in_anim</item>
        <item name="android:windowExitAnimation">@anim/dialog_out_anim</item>
    </style>

3、res下创建anim文件创建dialog_in_anim.xml和dialog_out_anim.xml
1、第一个

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromXDelta="0"
        android:fromYDelta="1000"
        android:toXDelta="0"
        android:toYDelta="0" />
</set>

2、第二个

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromXDelta="0"
        android:fromYDelta="0"
        android:toXDelta="0"
        android:toYDelta="1000" />
</set>
