Android自定义仿ios的toast提示（三）

仿ios的自定义toast。

说明：

一，使用的Androidstudio版本为3.4

二，使用说明。直接增加依赖。然后看本文第二大条。

allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

dependencies {
            implementation 'com.github.mamumu:mmToast:1.0'
    }

展示效果:

现在正式开始

1，核心activity和对应的布局文件。

package com.mumu.toast;

import android.content.Context;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

 */
public class MMToast extends Toast {

    public MMToast(Context context) {
        super(context);
    }

    public static class Builder {
        private Context context;
        private String message;
        private boolean isSuccess = true;

        public Builder(Context context) {
            this.context = context;
        }

        /**
         * 设置toast的内容
         *
         * @param message
         * @return
         */
        public Builder setMessage(String message) {
            this.message = message;
            return this;
        }

        /**
         * 是否是显示成功的toast，true:成功 false:失败
         *
         * @param isSuccess
         * @return
         */
        public Builder setSuccess(boolean isSuccess) {
            this.isSuccess = isSuccess;
            return this;
        }

        public MMToast create() {
            LayoutInflater inflater = LayoutInflater.from(context);
            View view = inflater.inflate(R.layout.dialog_toast, null);
            MMToast mmToast = new MMToast(context);
            TextView msgText = view.findViewById(R.id.t_text);
            ImageView imageView = view.findViewById(R.id.t_image);
            if (!message.isEmpty()) {
                msgText.setText(message);
            }
            if (isSuccess) {
                imageView.setImageResource(R.drawable.ic_success);
            } else {
                imageView.setImageResource(R.drawable.ic_failure);
            }

            mmToast.setView(view);
            mmToast.setDuration(Toast.LENGTH_SHORT);
            mmToast.setGravity(Gravity.CENTER,0,0);
            return mmToast;
        }
    }
}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/dialog_loading_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="70dp"
        android:background="@drawable/shape_bg"
        android:gravity="center"
        android:orientation="vertical"
        android:minWidth="80dp"
        android:paddingLeft="5dp"
        android:paddingTop="5dp"
        android:paddingRight="5dp"
        android:paddingBottom="5dp">

        <ImageView
            android:id="@+id/t_image"
            android:layout_width="30dp"
            android:layout_height="30dp" />

        <TextView
            android:id="@+id/t_text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:text="加载成功"
            android:textColor="#ffffff"
            android:textSize="14sp" />
    </LinearLayout>

</LinearLayout>

2，如何使用。一，直接在自己的BaseActivity中增加showToastSuccess()和showToastFailure()方法。如下第一段代码所示。二，MainActivity继承BaseActivity，直接使用对应的方法。

package com.mumu.mmtoast.base;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;

import com.mumu.toast.MMToast;


/**
 * @author : zlf
 * date    : 2019/4/17
 * github  : https://github.com/mamumu
 * blog    : https://www.jianshu.com/u/281e9668a5a6
 */
public class BaseActivity extends AppCompatActivity {

    private MMToast mmToast;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

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

    @Override
    protected void onPause() {
        super.onPause();
    }

    @Override
    protected void onResume() {
        super.onResume();
    }

    protected void showToastSuccess(String msg) {
        if (mmToast == null) {
            MMToast.Builder builder=new MMToast.Builder(this)
                    .setMessage(msg)
                    .setSuccess(true);
            mmToast=builder.create();
        }else {
            mmToast.cancel();
            MMToast.Builder builder=new MMToast.Builder(this)
                    .setMessage(msg)
                    .setSuccess(true);
            mmToast=builder.create();
        }
        mmToast.show();
    }

    protected void showToastFailure(String msg) {
        if (mmToast == null) {
            MMToast.Builder builder=new MMToast.Builder(this)
                    .setMessage(msg)
                    .setSuccess(false);
            mmToast=builder.create();
        }else {
            mmToast.cancel();
            MMToast.Builder builder=new MMToast.Builder(this)
                    .setMessage(msg)
                    .setSuccess(false);
            mmToast=builder.create();
        }
        mmToast.show();
    }
}

package com.mumu.mmtoast;

import android.os.Bundle;
import android.view.View;

import com.mumu.mmtoast.base.BaseActivity;

import butterknife.ButterKnife;
import butterknife.OnClick;

public class MainActivity extends BaseActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.bind(this);
        initView();
    }

    private void initView() {
    }

    @OnClick({R.id.button3, R.id.button4})
    public void onViewClicked(View view) {
        switch (view.getId()) {
            case R.id.button3:
                showToastSuccess("加载成功");
                break;
            case R.id.button4:
                showToastFailure("加载失败");
                break;
        }
    }
}

3，对应github地址

4，我后面将dialog（一），loading（二）和toast（三）做了统一封装链接如下，推荐使用：
