Question

我的应用程序中有一个自定义对话框但是当我点击对话框的按钮时它们不起作用！

我想在导航抽屉的一个项目中显示对话框那是代码：

dialog = new Dialog(MaterialCardsActivity.this);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(true);
        dialog.setContentView(R.layout.dialog_mail);
        dialog.show();

我该如何解决？

Custom_Dialog.java

package com.example.material.amirj;

import android.app.Dialog;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.Window;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;


public class Dialog_Custom extends AppCompatActivity {

private EditText caption;
private Dialog dialog;
private EditText text;
private Button send,cancel;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.dialog_mail);


    dialog = new Dialog(Dialog_Custom.this);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setCancelable(true);
    dialog.setContentView(R.layout.dialog_mail);

    caption = (EditText) dialog.findViewById(R.id.txt_caption_dialoge);
    text = (EditText) dialog.findViewById(R.id.txt_text_dialoge);
    send = (Button) dialog.findViewById(R.id.btn_send_email);
    cancel = (Button) dialog.findViewById(R.id.btn_cancel_dialog);

    send.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent i = new Intent(Intent.ACTION_SEND);
            i.setType("message/rfc822");
            i.putExtra(Intent.EXTRA_EMAIL, new String[]{"titandevelopers98@gmail.com"});
            i.putExtra(Intent.EXTRA_SUBJECT, "" + caption.getText());
            i.putExtra(Intent.EXTRA_TEXT, "" + text.getText());
            try {
                startActivity(Intent.createChooser(i, "ارسال ایمیل با ..."));
            } catch (android.content.ActivityNotFoundException ex) {
                Toast.makeText(Dialog_Custom.this, "برنامه ای از ازسال ایمیل پشتیبانی نمیکند.", Toast.LENGTH_SHORT).show();
            }
        }

    });
    cancel.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();

        }
    });
  dialog.show();
}
}

试试这个，

dialog_main.xml

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

<Button
    android:id="@+id/buttonClick"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Click To Show Custom Dialog" />

</LinearLayout>

dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<ImageView
    android:id="@+id/imageDialog"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginRight="6dp" />

<TextView
    android:id="@+id/textDialog"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#FFF"
    android:layout_toRightOf="@+id/imageDialog"/>

 <Button
    android:id="@+id/okButton"
    android:layout_width="100px"
    android:layout_height="wrap_content"
    android:text="Ok"
    android:layout_marginTop="5dp"
    android:layout_marginRight="5dp"
    android:layout_below="@+id/textDialog"
    android:layout_toRightOf="@+id/imageDialog"
    />

</RelativeLayout>

CustomDialog.java

公共类CustomDialog扩展了Activity {

private Button btnClick;

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.custom_dialog_main);

    btnClick = (Button) findViewById(R.id.btnClick);

    // add listener to button 
    buttonClick.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            // Create custom dialog object
            final Dialog dialog = new Dialog(CustomDialog.this);
            // Include dialog.xml file
            dialog.setContentView(R.layout.dialog);
            // Set dialog title
            dialog.setTitle("Custom Dialog");

            // set values for custom dialog components - text, image and button
            TextView text = (TextView) dialog.findViewById(R.id.textDialog);
            text.setText("Custom dialog");
            ImageView image = (ImageView) dialog.findViewById(R.id.imageDialog);
            image.setImageResource(R.drawable.image0);

            dialog.show();

            Button okButton = (Button) dialog.findViewById(R.id.declineButton);
            // if decline button is clicked, close the custom dialog
            okButton.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    // Close dialog
                    dialog.dismiss();
                }
            });


        }

    });

  }

}

快乐的编码..！
