Android—自定义Dialog

1、Dialog调用的地方

Dialog dialog = new Dialog(context);
dialog.setClickListener(onclickListener);
dialog.show();

Dialog.OnclickListener onclickListener =
            new Dialog.onclickListener(){
                @Override
                public void confirmListener() {

                }

                @Override
                public void cancelListener() {

                }
            };

 

 1、继承Dialog，重写onCreate()函数

public class Dialog extends android.app.Dialog{
    private Context mContext;
    private OnclickListener mClickListener;

    public Dialog(Context context) {
        super(context,R.style.Dialog);//自定义dialog样式
        mContext = context;
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        initView();

        WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
        layoutParams.width = mContext.getResources().getDimensionPixelSize(R.dimen.size_292dp);
        layoutParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
        layoutParams.dimAmount = 0.25f;//背景透明度
        getWindow().setAttributes(layoutParams);

        setCancelable(false);//点击返回键和屏幕空白处对话框不消失

    }

    private void initView() {
        LayoutInflater inflater = LayoutInflater.from(mContext);
        View contentView = inflater.inflate(R.layout.order_secondary_confirm_dialog_layout, null);
        setContentView(contentView);

        mTvPayMoney = findViewById(R.id.tv_order_confirm_sendory_dialog_pay_money);
        mBtnCancel = findViewById(R.id.btn_order_confirm_sendory_dialog_cancel);
        mBtnConfirm = findViewById(R.id.btn_order_confirm_sendory_dialog_confirm);

        mBtnConfirm.setOnClickListener(this);
        mBtnCancel.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.btn_order_confirm_sendory_dialog_confirm:
                if(mClickListener != null) {
                    mClickListener.confirmListener();
                }
                dismiss();
                break;
            case R.id.btn_order_confirm_sendory_dialog_cancel:
                if(mClickListener != null) {
                    mClickListener.cancelListener();
                }
                dismiss();
                break;
        }
    }


    public void setClickListener(SecondaryDialogOnclickListener listener){
        mClickListener = listener;
    }

    public interface OnclickListener{
        public void confirmListener();
        public void cancelListener();
    }

}

2、Dialog样式

    <style name="Dialog" parent="android:Theme">
        <item name="android:windowBackground">@android:color/transparent</item>
        <!-- <item name="android:windowFullscreen">true</item> -->
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowNoTitle">true</item>
    </style>

 

 3、Dialog布局

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"    
    android:layout_height="wrap_content"
    android:background="@drawable/round_bg"
    android:orientation="vertical">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="30dp"
        android:text="确认支付"
        android:textSize="19dp"
        android:textColor="#352d2b"
        android:textStyle="bold"/>

    <TextView
        android:id="@+id/tv_order_confirm_sendory_dialog_pay_money"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="14dp"
        android:layout_marginBottom="30dp"
        android:text="支付金额"
        android:textColor="#352d2b"
        android:textSize="15dp" />

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="#f3f3f3"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="50dp" >

        <Button
            android:id="@+id/btn_order_confirm_sendory_dialog_cancel"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@drawable/alert_dialog_leftbottom_bg"
            android:text="取消"
            android:textColor="#868180"
            android:textSize="16dp" />

        <Button
            android:id="@+id/btn_order_confirm_sendory_dialog_confirm"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@drawable/alert_dialog_rightbottom_bg"
            android:text="确认"
            android:textColor="#BFAB8E"
            android:textSize="16dp" />

    </LinearLayout>

</LinearLayout>

4、Dialog背景
