Android自定义的仿ios的loading弹窗（二） Android自定义的仿ios的loading弹窗

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' }

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; /** * @author : zlf * date: 2019/4/17 * github: https://github.com/mamumu * blog: https://www.jianshu.com/u/281e9668a5a6 */ 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。

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

@android:color/transparent @null true true true @null @android:style/Animation.Dialog true 0.6

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 demo地址：https://github.com/mamumu/mmLoading 6，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： https://www.jianshu.com/p/9259ad7f857b
