一个简单的DialogFragment用例(3)--通用型

作者: 颤抖的闪电 | 来源:发表于2019-10-25 15:54 被阅读0次

前言：一个比较通用型的弹出框，献丑了。
核心类AbstractDialog，这是一个虚基类，用于继承使用，当然自身也已经包含了title、content、左按钮、右按钮的等等基本UI雏形，用户只需要继承重写setLayoutView（）就可以自定义界面了，灵活的很。
源码就这几个类，很通俗易懂，可以自己手动修改成自己想要的效果，这里更多的只是提供了一个我自己码代码的写法，或者是风格吧，或只是提供一个参考。

自定义操作如下：
自定义Dialog类，继承AbstractDialog，重写setLayoutView，引入自己的layout.xml，灵活的很，根据以下代码，相信你一看就懂。


import android.support.v4.app.FragmentActivity;
import android.text.method.ScrollingMovementMethod;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

import com.yaoxiaowen.download.sample.R;


public class MDialog extends AbstractDialog {

    @Override
    public View setLayoutView(final FragmentActivity activity) {
        LayoutInflater inflater = activity.getLayoutInflater();
        final View view = inflater.inflate(R.layout.m_dialog_layout, null);
        TextView tv_dialog_title = view.findViewById(R.id.abstract_tv_dialog_title);
        ImageView img_dialog_cancle = view.findViewById(R.id.img_dialog_cancle);

        //中部
        TextView tv_dialog_content = view.findViewById(R.id.tv_dialog_content);
        tv_dialog_content.setMovementMethod(ScrollingMovementMethod.getInstance());

        //底部
        TextView tv_right = view.findViewById(R.id.tv_right);
        TextView tv_left = view.findViewById(R.id.tv_left);


        img_dialog_cancle.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(activity,"点击取消",Toast.LENGTH_LONG).show();
            }
        });

        tv_right.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(activity,"点击右边",Toast.LENGTH_LONG).show();
            }
        });

        tv_left.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(activity,"点击左边",Toast.LENGTH_LONG).show();
            }
        });

        return view;
    }

使用方法如下：

new MDialog().build(FirstActivity.this)
                        .setTitleVisible(false) //配置默认头部是否可见

                        .setRightVisible(false)//配置默认右按钮是否可见
                        .setOnClickCancle(new AbstractDialog.Onclick() {  //配置右上角删除按钮监听函数
                            @Override
                            public void onClick() {
                                Toast.makeText(FirstActivity.this,"点击取消",Toast.LENGTH_LONG).show();
                            }
