本文介绍了一种带有模糊背景效果的自定义Dialog实现方法，包括样式配置、基础代码框架及使用方式。通过设置特定的样式属性，如背景透明度和模糊效果，实现了Dialog窗口的美观展示。同时提供了一个具体的Dialog实例——DeleteDialog，展示了如何使用数据绑定和自定义接口来增强交互性和功能性。

使用环境：

需要dialog的时候

使用方法：

1 样式：

<color name="transparent">#00000000</color>

<style name="TaoDialog" parent="@android:style/Theme.Dialog">
    <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">false</item><!--半透明-->
    <item name="android:windowNoTitle">true</item><!--无标题-->
    <item name="android:windowBackground">@color/transparent</item><!--背景透明-->
    <item name="android:backgroundDimEnabled">true</item><!--模糊-->
</style>

public class BaseDialog extends Dialog implements Observable {
    private transient PropertyChangeRegistry mCallbacks;

    @Override
    public void addOnPropertyChangedCallback(OnPropertyChangedCallback callback) {
        synchronized (this) {
            if (mCallbacks == null) {
                mCallbacks = new PropertyChangeRegistry();
            }
        }
        mCallbacks.add(callback);
    }

    @Override
    public void removeOnPropertyChangedCallback(OnPropertyChangedCallback callback) {
        synchronized (this) {
            if (mCallbacks == null) {
                return;
            }
        }
        mCallbacks.remove(callback);
    }

    public void notifyPropertyChanged(int fieldId) {
        synchronized (this) {
            if (mCallbacks == null) {
                return;
            }
        }
        mCallbacks.notifyCallbacks(this, fieldId, null);
    }


    private BaseActivity activity;
    private float alpha = 1;
    private Object tag;

    public void setTag(Object tag) {
        this.tag = tag;
    }

    public Object getTag() {
        return tag;
    }

    public void setShowingAlpha(float alpha) {
        this.alpha = alpha;
    }

    public BaseDialog(Context context) {
//        super(context, R.style.Translucent_Dialog);
        super(context, R.style.TaoDialog);
        if (context instanceof BaseActivity) this.activity = (BaseActivity) context;
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setCancelable(true);
        WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
        layoutParams.width = WindowManager.LayoutParams.WRAP_CONTENT;
        layoutParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
        getWindow().setAttributes(layoutParams);
    }

    public Context getActivity() {
        if (activity != null) return activity;
        else return super.getContext();
    }

    @Override
    public void show() {
        handler.removeMessages(0);
        handler.sendEmptyMessage(1);
    }

    public void showDelayed(long time) {
        if (time == -1) handler.sendEmptyMessageDelayed(0, 10 * 1000);
        else handler.sendEmptyMessageDelayed(0, time);
        this.show();
    }

    @Override
    public void dismiss() {
        handler.removeMessages(0);
        handler.sendEmptyMessage(2);
    }

    private Handler handler = new Handler(Looper.getMainLooper()) {
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case 0:
                    if (!isShowing()) return;
                    dismiss();
                    break;
                case 1:
                    if (isShowing()) return;
                    BaseDialog.super.show();
                    if (activity != null) {
                        if (activity.isFinishing()) return;
                        if (alpha != 1) {
                            WindowManager.LayoutParams params = activity.getWindow().getAttributes();
                            params.alpha = alpha;
                            activity.getWindow().setAttributes(params);
                        }
                    }
                    break;
                case 2:
                    if (!isShowing()) return;
                    BaseDialog.super.dismiss();
                    if (activity == null || activity.isFinishing()) return;
                    if (alpha != 1) {
                        WindowManager.LayoutParams params = activity.getWindow().getAttributes();
                        params.alpha = 1f;
                        activity.getWindow().setAttributes(params);
                    }
                    break;

            }
        }
    };
}

2 一个简单的布局：

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

    <data>
        <variable
            name="delete"
            type="com.yarui.app.client.ui.view.dialog.DeleteDialog"/>
    </data>

    <LinearLayout
        android:orientation="vertical"
        android:background="@drawable/mainbackground"
        android:layout_width="@dimen/threehundred"
        android:layout_height="@dimen/oneHundredninety">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="@dimen/sixty"
            android:gravity="center"
            android:text="@string/lookimage"
            android:textSize="@dimen/textSizeA"
            android:textColor="@color/text_block"
            android:onClick="@{delete.lookPoint}"
            />

        <include layout="@layout/one"/>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="@dimen/sixty"
            android:gravity="center"
            android:text="@string/deletePhoto"
            android:textSize="@dimen/textSizeA"
            android:textColor="@color/text_block"
            android:onClick="@{delete.deletePoint}"
            />

        <include layout="@layout/henglineten"/>

        <TextView
            android:onClick="@{delete.cancelPoint}"
            android:layout_width="match_parent"
            android:layout_height="@dimen/sixty"
            android:gravity="center"
            android:text="@string/cancel"
            android:textSize="@dimen/textSizeA"
            android:textColor="@color/text_block"
            />

    </LinearLayout>

</layout>

draw able：

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

    <solid android:color="@color/FFFFFF"/>
    <corners android:radius="@dimen/twenty"/>
    <stroke android:color="@color/FFFFFF" android:width="@dimen/one"/>

</shape>

public class DeleteDialog extends BaseDialog {

    private Context mcontext;
    private DialogDeletephotoBinding deletephotoBinding;
    private onCheckItemClick onCheckItemClick;

    public DeleteDialog(Context context) {
        super(context);
        this.mcontext = context;
        deletephotoBinding = DataBindingUtil.inflate(LayoutInflater.from(mcontext), R.layout.dialog_deletephoto,null,false);
        deletephotoBinding.setDelete(this);
        setContentView(deletephotoBinding.getRoot());
    }

    public void setOnCheckItemClick(onCheckItemClick onCheckItemClick) {
        this.onCheckItemClick = onCheckItemClick;
    }

    public void lookPoint(View view) {
        if (onCheckItemClick != null) {
            onCheckItemClick.onConfirmClick();
        }
        dismiss();
    }

    public void deletePoint(View view) {
        if (onCheckItemClick != null) {
            onCheckItemClick.onCancelClick();
        }
        dismiss();
    }

    public void cancelPoint(View view){
        if (onCheckItemClick != null) {
            onCheckItemClick.onCloseClick();
        }
        dismiss();
    }

}

在activity中使用

DeleteDialog deleteDialog = new DeleteDialog(LoginActivity.this);
deleteDialog.show();

本文中使用了初级的databinding，

自定义的接口：

public interface onCheckItemClick {

    void onCancelClick();

    void onConfirmClick();

    void onCloseClick();

}

思路不清晰……作为笔记使用。

重点 1 显示模糊背景的style

2 dialog的base代码

3 dialog的用法
