Android xml布局之dialog

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
