嘿,今天的你过的还好吗,今天分享自己的BaseFragment内容,仅供参考
package com.example.mall.base;

import android.annotation.SuppressLint;
import android.content.Context;
import android.os.Bundle;
import android.os.Looper;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Toast;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;

public abstract class BaseFragment extends Fragment {
    //获取TAG的fragment名称
    protected final String TAG = this.getClass().getSimpleName();
    public Context context;
    /**
     * 封装toast对象
     */
    private Toast toast;

    @Override
    public void onAttach(@NonNull Context context) {
        super.onAttach(context);
        context = context;
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(layoutId(),container,false);

        ButterKnife.bind(this,view);
        initView(view);
        initData(context);
        return view;
    }

    /**
     * 初始化布局
     * @return 布局id
     */
    protected abstract int layoutId();

    /**
     * 初始化控件
     * @param view 布局view
     */
    protected abstract void initView(View view);

    /**
     * 初始化,绑定数据
     * @param context 上下文
     */
    protected abstract void initData(Context context);

    /**
     * 保证同一按钮在1秒内只响应一次点击事件
     */
    public abstract class OnSingleClickListener implements View.OnClickListener {
        //两次点击按钮的最小间隔,目前为1000
        private static final int MIN_CLICK_DELAY_TIME = 1000;
        private long lastClickTime;

        public abstract void onSingleClick(View view);

        @Override
        public void onClick(View v) {
            long curClickTime = System.currentTimeMillis();
            if ((curClickTime - lastClickTime) >= MIN_CLICK_DELAY_TIME) {
                lastClickTime = curClickTime;
                onSingleClick(v);
            }
        }
    }

    /**
     * 同一按钮在短时间内可重复响应点击事件
     */
    public abstract class OnMultiClickListener implements View.OnClickListener {
        public abstract void onMultiClick(View view);

        @Override
        public void onClick(View v) {
            onMultiClick(v);
        }
    }

    /**
     * 显示提示  toast
     *
     * @param msg 提示信息
     */
    @SuppressLint("ShowToast")
    public void showToast(String msg) {
        try {
            if (null == toast) {
                toast = Toast.makeText(context, msg, Toast.LENGTH_SHORT);
            } else {
                toast.setText(msg);
            }
            toast.show();
        } catch (Exception e) {
            e.printStackTrace();
            //解决在子线程中调用Toast的异常情况处理
            Looper.prepare();
            Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();
            Looper.loop();
        }
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }
}

没更新动态或者频繁更新动态的时候都是在认真生活
