自定义宽高DialogFragment带回调

step1: MainActivity 首页

package com.example.dialogfragmentdemotwo;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TestingDialogFragment testingDialogFragment = new TestingDialogFragment();
        testingDialogFragment.show(getFragmentManager(), "");
        testingDialogFragment.onSetClickDialogListener(new TestingDialogFragment.SetOnClickDialogListener() {

            @Override
            public void onClickDialogListener(int type, boolean boolClick, String content) {
                Log.e("TAG", "onClickDialogListener： " + type + "\t" + boolClick + "\t" + content);
            }
        });
    }
}

step2: dialogfragmentdemotwo\TestingDialogFragment.java 弹框页

package com.example.dialogfragmentdemotwo;

import android.app.DialogFragment;
import android.content.DialogInterface;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.TextView;
import androidx.annotation.Nullable;

public class TestingDialogFragment extends DialogFragment {
    protected TextView tv_tip;
    protected Button btn_dialog;
    private SetOnClickDialogListener mSetOnClickListener;

    public void onSetClickDialogListener(SetOnClickDialogListener listener) {
        this.mSetOnClickListener = listener;
    }

    public interface SetOnClickDialogListener {
        void onClickDialogListener(int type, boolean boolClick, String content);
    }

    @Override
    public void onStart() {
        super.onStart();
        if (getDialog() != null && getDialog().getWindow() != null) {
            Window window = getDialog().getWindow();
            WindowManager.LayoutParams params = window.getAttributes();
            params.width = WindowManager.LayoutParams.MATCH_PARENT;
            params.height = WindowManager.LayoutParams.MATCH_PARENT;
            window.setAttributes(params);
        }
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        if (getDialog() != null && getDialog().getWindow() != null) {
            getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
            getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
            getDialog().setCanceledOnTouchOutside(true);
        }
        View mView = inflater.inflate(R.layout.dialog_test, container, false);
        tv_tip = mView.findViewById(R.id.tv_tip);
        btn_dialog = mView.findViewById(R.id.btn_dialog);

        btn_dialog.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                getDialog().cancel();
                if (mSetOnClickListener != null) {
                    mSetOnClickListener.onClickDialogListener(0, true, "test");
                }
            }
        });

        return mView;
    }

    @Override
    public void onCancel(DialogInterface dialog) {
        super.onCancel(dialog);
    }

    @Override
    public void onDismiss(DialogInterface dialog) {
        super.onDismiss(dialog);
    }
}

step3: D:\workspace\DialogFragmentDemoTwo\app\src\main\res\layout\dialog_test.xml 弹框布局

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

    <RelativeLayout
        android:layout_width="320dp"
        android:layout_height="450dp"
        android:background="@drawable/radius_border"
        android:orientation="vertical"
        android:padding="10dp">

        <TextView
            android:id="@+id/tv_tip"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:layout_marginTop="5dp"
            android:text="@string/app_name"
            android:textColor="#333333"
            android:textSize="14sp"
            tools:text="正在测试XXX (1/5)" />

        <Button
            android:id="@+id/btn_dialog"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            android:layout_marginBottom="30dp"
            android:text="@string/app_name" />

    </RelativeLayout>

</LinearLayout>

step4: 圆角边框 D:\workspace\DialogFragmentDemoTwo\app\src\main\res\drawable\radius_border.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/white"/>
    <!--  圆角 <corners android:radius="15dp"/>-->
    <corners
        android:topRightRadius="15dp"
        android:bottomRightRadius="15dp"
        android:bottomLeftRadius="15dp"
        android:topLeftRadius="15dp"/>
    <stroke android:width="1dp" android:color="#eeeeee"/>
</shape>

run，success！
