在线直播源码，自定义AlertDialog设置宽高并去掉默认的边框

1、先写一个自定义的AlertDialog。

<br>package com.phone.common_library.dialog;<br> <br>import android.annotation.SuppressLint;<br>import android.content.Context;<br>import android.content.DialogInterface;<br>import android.view.Gravity;<br>import android.view.LayoutInflater;<br>import android.view.View;<br>import android.view.Window;<br>import android.view.WindowManager;<br>import android.widget.TextView;<br> <br>import androidx.annotation.NonNull;<br>import androidx.appcompat.app.AlertDialog;<br> <br>import com.phone.common_library.R;<br>import com.phone.common_library.callback.OnCommonSingleParamCallback;<br>import com.phone.common_library.callback.OnItemViewClickListener;<br> <br>public class StandardDialog {<br> <br>    private AlertDialog alertDialog;<br> <br>    private TextView tevTitle;<br>    private TextView tevContent;<br>    private View viewHorizontalLine;<br>    private TextView tevCancel;<br>    private View viewVerticalLine;<br>    private TextView tevOk;<br> <br> <br>    @SuppressLint("RestrictedApi")<br>    public StandardDialog(@NonNull Context context) {<br>        View view = LayoutInflater.from(context).inflate(R.layout.dialog_standard, null, false);<br>        tevTitle = (TextView) view.findViewById(R.id.tev_title);<br>        tevContent = (TextView) view.findViewById(R.id.tev_content);<br>        viewHorizontalLine = (View) view.findViewById(R.id.view_horizontal_line);<br>        tevCancel = (TextView) view.findViewById(R.id.tev_cancel);<br>        viewVerticalLine = (View) view.findViewById(R.id.view_vertical_line);<br>        tevOk = (TextView) view.findViewById(R.id.tev_ok);<br> <br> <br>        //设置R.style.dialog_decimal_style和setView(view, 0, 0, 0, 0)就可以去掉<br>        //AlertDialog的默认边框，此时AlertDialog的layout的宽高就是AlertDialog的宽高<br>        alertDialog = new AlertDialog.Builder(context, R.style.standard_dialog_style)<br>                .setView(view)<br>                .create();<br>        tevCancel.setOnClickListener(v -> {<br>            onItemViewClickListener.onItemClickListener(0, v);<br>        });<br>        tevOk.setOnClickListener(v -> {<br>            onItemViewClickListener.onItemClickListener(1, v);<br>        });<br>        alertDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {<br>            @Override<br>            public void onCancel(DialogInterface dialog) {<br>                onCommonSingleParamCallback.onSuccess("");<br>            }<br>        });<br>        alertDialog.show();<br> <br>        Window window = alertDialog.getWindow();<br>        if (window != null) {<br>//            window.setBackgroundDrawableResource(android.R.color.transparent);<br>            // 取消这些边框的关键代码<br>            window.setBackgroundDrawable(null);<br>            window.setGravity(Gravity.CENTER);<br>//            window.setWindowAnimations(R.style.PictureThemeDialogWindowStyle);<br>            WindowManager.LayoutParams params = window.getAttributes();<br>            window.setAttributes(params);<br>            //把 DecorView 的默认 padding 取消，同时 DecorView 的默认大小也会取消<br>            window.getDecorView().setPadding(0, 0, 0, 0);<br>        }<br>    }<br> <br>    public void setTevContent(String content) {<br>        tevContent.setText(content);<br>    }<br> <br>    public void setTevCancelHide() {<br>        viewVerticalLine.setVisibility(View.GONE);<br>        tevCancel.setVisibility(View.GONE);<br>    }<br> <br>    public void setCannotHide() {<br>        alertDialog.setCancelable(false);<br>        alertDialog.setCanceledOnTouchOutside(false);<br>    }<br> <br>    public void hideStandardDialog() {<br>        if (alertDialog != null) {<br>            alertDialog.dismiss();<br>            alertDialog = null;<br>        }<br>    }<br> <br>    private OnItemViewClickListener onItemViewClickListener;<br> <br>    public void setOnItemViewClickListener(OnItemViewClickListener onItemViewClickListener) {<br>        this.onItemViewClickListener = onItemViewClickListener;<br>    }<br> <br>    private OnCommonSingleParamCallback<String> onCommonSingleParamCallback;<br> <br>    public void setOnCommonSingleParamCallback(OnCommonSingleParamCallback<String> onCommonSingleParamCallback) {<br>        this.onCommonSingleParamCallback = onCommonSingleParamCallback;<br>    }<br> <br>}

2、AlertDialog的layout。

<br><?xml version="1.0" encoding="utf-8"?><br><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"<br>    xmlns:tools="http://schemas.android.com/tools"<br>    android:layout_width="@dimen/dp_300"<br>    android:layout_height="@dimen/dp_240"<br>    android:background="@drawable/corners_14_color_white"<br>    android:orientation="vertical"><br> <br>    <!-- 注意：这里一定要写一个布局，这个布局和本布局的根布局宽高相同，要写固定宽高，不要使用match_parent，不然宽高可能会失效 --><br>    <LinearLayout<br>        android:layout_width="@dimen/dp_300"<br>        android:layout_height="@dimen/dp_240"<br>        android:orientation="vertical"<br>        tools:ignore="UselessParent"><br> <br>        <View<br>            android:layout_width="match_parent"<br>            android:layout_height="@dimen/dp_20" /><br> <br>        <TextView<br>            android:layout_width="match_parent"<br>            android:layout_height="@dimen/dp_40"<br>            android:layout_gravity="center_horizontal"<br>            android:gravity="center"<br>            android:paddingStart="@dimen/dp_10"<br>            android:paddingEnd="@dimen/dp_10"<br>            android:text="Decimal"<br>            android:textColor="@color/blue"<br>            android:textSize="@dimen/sp_16" /><br> <br>        <View<br>            android:layout_width="match_parent"<br>            android:layout_height="@dimen/dp_20" /><br> <br>        <EditText<br>            android:id="@+id/edt_input"<br>            android:layout_width="@dimen/dp_240"<br>            android:layout_height="@dimen/dp_40"<br>            android:layout_gravity="center_horizontal"<br>            android:background="@drawable/corners_14_color_white_stroke_1_color_80000000"<br>            android:gravity="center_vertical"<br>            android:paddingStart="@dimen/dp_15"<br>            android:paddingEnd="@dimen/dp_15"<br>            android:textColor="@color/colorBlack333"<br>            android:textSize="@dimen/sp_16" /><br> <br>        <View<br>            android:layout_width="match_parent"<br>            android:layout_height="@dimen/dp_20" /><br> <br>        <FrameLayout<br>            android:layout_width="@dimen/dp_200"<br>            android:layout_height="@dimen/dp_40"<br>            android:layout_gravity="center_horizontal"><br> <br>            <TextView<br>                android:id="@+id/tev_cancel"<br>                android:layout_width="@dimen/dp_80"<br>                android:layout_height="@dimen/dp_40"<br>                android:layout_gravity="start"<br>                android:background="@drawable/corners_14_color_white_stroke_1_color_80000000"<br>                android:gravity="center"<br>                android:paddingStart="@dimen/dp_10"<br>                android:paddingEnd="@dimen/dp_10"<br>                android:text="cancel"<br>                android:textColor="@color/color_80000000"<br>                android:textSize="@dimen/sp_16" /><br> <br>            <TextView<br>                android:id="@+id/tev_confirm"<br>                android:layout_width="@dimen/dp_80"<br>                android:layout_height="@dimen/dp_40"<br>                android:layout_gravity="end"<br>                android:background="@drawable/corners_14_color_white_stroke_1_color_blue"<br>                android:gravity="center"<br>                android:paddingStart="@dimen/dp_10"<br>                android:paddingEnd="@dimen/dp_10"<br>                android:text="confirm"<br>                android:textColor="@color/blue"<br>                android:textSize="@dimen/sp_16" /><br> <br>        </FrameLayout><br>    </LinearLayout><br> <br></LinearLayout>
