Android中自定义DialogFragment解决宽度和高度问题

Android中自定义DialogFragment解决宽度和高度问题但是我们很多时候想把DialogFragment的高度固定，那么我们需要设置DialogFragment的高度，在Fragment的onResume()声明周期方法中设置window的宽高即可。

    @Override
    public void onResume() {
        super.onResume();
            getDialog().getWindow().setLayout(DeviceUtil.getDeviceWidth(), ResUtils.dp2px(295));
    }

设置DialogFrament 从底部弹出，并且弹出动画为向上滑出，消失动画为向下滑出

WindowManager.LayoutParams params = getDialog().getWindow()
        .getAttributes();
params.gravity = Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL;
params.windowAnimations = R.style.bottomSheet_animation;
getDialog().getWindow().setAttributes(params);

完整的代码如下：

 @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        WindowManager.LayoutParams params = getDialog().getWindow()
                .getAttributes();
        params.gravity = Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL;
        params.windowAnimations = R.style.bottomSheet_animation;
        getDialog().getWindow().setAttributes(params);
        getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        getDialog().setCanceledOnTouchOutside(true);
        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        mContentView = inflater.inflate(R.layout.fragment_create_quick, container, false);
        return mContentView;
    }

    @Override
    public void onResume() {
        super.onResume();
       getDialog().getWindow().setLayout(DeviceUtil.getDeviceWidth(), HlyUtils.dp2px(380));
    }

 <style name="bottomSheet_animation" parent="@android:style/Animation">
        <item name="android:windowEnterAnimation">@anim/slide_in_bottom</item>
        <item name="android:windowExitAnimation">@anim/slide_out_bottom</item>
 </style>
