Android自定义的仿ios的loading弹窗（二）

laoding是每个app必备的。一般公司都会自定义。使用自己公司的吉祥物来展示。今天来写一个仿ios效果的loading。下一期会写一个自定义的toast。然后和前面写的弹窗一起组合成一个公共的依赖库。

说明：

一，使用的Androidstudio版本为3.3.2

二，使用说明。直接增加依赖。然后看本文的第四大条即可。

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

dependencies {
            implementation 'com.github.mamumu:mmLoading:1.1'
    }

展示效果:

现在正式开始

1，核心activity。

package com.mumu.loading;

import android.app.Dialog;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.WindowManager;
import android.widget.TextView;

 */
public class MMLoading extends Dialog {

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

    public MMLoading(Context context, int themeResId) {
        super(context, themeResId);
    }

    public static class Builder {

        private Context context;
        private String message;
        private boolean isShowMessage = true;
        private boolean isCancelable = false;
        private boolean isCancelOutside = false;

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

        /**
         * 设置提示信息
         * @param message
         * @return
         */

        public Builder setMessage(String message) {
            this.message = message;
            return this;
        }

        /**
         * 设置是否显示提示信息
         * @param isShowMessage
         * @return
         */
        public Builder setShowMessage(boolean isShowMessage) {
            this.isShowMessage = isShowMessage;
            return this;
        }

        /**
         * 设置是否可以按返回键取消
         *
         * @param isCancelable
         * @return
         */

        public Builder setCancelable(boolean isCancelable) {
            this.isCancelable = isCancelable;
            return this;
        }

        /**
         * 设置是否可以点击外部取消
         * @param isCancelOutside
         * @return
         */
        public Builder setCancelOutside(boolean isCancelOutside) {
            this.isCancelOutside = isCancelOutside;
            return this;
        }

        public MMLoading create() {
            LayoutInflater inflater = LayoutInflater.from(context);
            View view = inflater.inflate(R.layout.dialog_loading, null);
            MMLoading mmLoading = new MMLoading(context, R.style.MyDialogStyle);
            TextView msgText = (TextView) view.findViewById(R.id.tipTextView);
            if (isShowMessage) {
                msgText.setText(message);
            } else {
                msgText.setVisibility(View.GONE);
            }
            mmLoading.setContentView(view);
            mmLoading.setCancelable(isCancelable);
            mmLoading.setCanceledOnTouchOutside(isCancelOutside);
            //实现loading的透明度
//            WindowManager.LayoutParams lp=mmLoading.getWindow().getAttributes();
//            lp.alpha = 0.6f;
//            mmLoading.getWindow().setAttributes(lp);
            return mmLoading;
        }
    }
}

2，对应的布局文件。

<?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="90dp"
        android:background="@drawable/loading_bg"
        android:gravity="center"
        android:orientation="vertical"
        android:minWidth="100dp"
        android:paddingLeft="15dp"
        android:paddingTop="10dp"
        android:paddingRight="15dp"
        android:paddingBottom="10dp">

        <ProgressBar
            android:layout_width="35dp"
            android:layout_height="35dp"
            android:layout_gravity="center_horizontal"
            android:indeterminateBehavior="repeat"
            android:indeterminateDrawable="@drawable/dialog_loading"
            android:indeterminateOnly="true" />

        <TextView
            android:id="@+id/tipTextView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:text="加载中..."
            android:textColor="#f0f0f0"
            android:textSize="15sp" />
    </LinearLayout>

</LinearLayout>

3，对应的style样式。这注意：backgroundDimAmount：调节蒙层的透明度0-1。

<resources>

    <!--loading样式-->
    <!--backgroundDimAmount：调节蒙层的透明度0-1-->
    <style name="MyDialogStyle">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:backgroundDimEnabled">true</item>
        <item name="android:backgroundDimAmount">0.6</item>
    </style>

</resources>

4，如何使用。一，直接在自己的BaseActivity中增加showLoading()和hideLoading()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.mmloading.base;

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

import com.mumu.loading.MMLoading;

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

    private MMLoading mmLoading;

    @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 showLoading() {
        if (mmLoading == null) {
            MMLoading.Builder builder = new MMLoading.Builder(this)
                    .setMessage("加载中...")
                    .setCancelable(false)
                    .setCancelOutside(true);
            mmLoading = builder.create();
        }else {
            mmLoading.dismiss();
            MMLoading.Builder builder = new MMLoading.Builder(this)
                    .setMessage("加载中...")
                    .setCancelable(false)
                    .setCancelOutside(true);
            mmLoading = builder.create();
        }
        mmLoading.show();
    }

    protected void showLoading(String msg) {
        if (mmLoading == null) {
            MMLoading.Builder builder = new MMLoading.Builder(this)
                    .setMessage(msg)
                    .setCancelable(false)
                    .setCancelOutside(true);
            mmLoading = builder.create();
        }else {
            mmLoading.dismiss();
            MMLoading.Builder builder = new MMLoading.Builder(this)
                    .setMessage(msg)
                    .setCancelable(false)
                    .setCancelOutside(false);
            mmLoading = builder.create();
        }
        mmLoading.show();
    }

    protected void hideLoading() {
        if (mmLoading != null && mmLoading.isShowing()) {
            mmLoading.dismiss();
        }
    }
}

package com.mumu.mmloading;

import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.Button;

import com.mumu.mmloading.base.BaseActivity;

import butterknife.BindView;
import butterknife.ButterKnife;
import butterknife.OnClick;

public class MainActivity extends BaseActivity {

    @BindView(R.id.button1)
    Button button1;
    @BindView(R.id.button2)
    Button button2;

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

    private void initView() {
    }


    @OnClick({R.id.button1, R.id.button2})
    public void onViewClicked(View view) {
        switch (view.getId()) {
            case R.id.button1:
                showLoading();
                //延迟3秒关闭
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        hideLoading();
                    }
                },3000);
                break;
            case R.id.button2:
                showLoading("正在校验信息");
                //延迟3秒关闭
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        hideLoading();
                    }
                },5000);
                break;
        }
    }
}

5，对应github地址
