                                Log.v("MOB1",mob1.getText().toString());                                
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Business Card",phoneArray);
                            }

                        }else if(!mob1.isChecked() && mob2.isChecked()) {
                            if(radioGrp.getCheckedRadioButtonId() == R.id.radioSms) {
                                String[] phoneArray = {mob2.getText().toString()};

                                Log.v("MOB2",mob2.getText().toString());
                                Log.v("Mobile No", ""+phoneArray.toString());

                        }else if(!mob1.isChecked() && !mob2.isChecked()) {
                            Toast.makeText(getApplicationContext(), "Select atleast one number", Toast.LENGTH_SHORT).show();
                        }                       
                    }
                });
                myDialog.show();
            }

        });
    }

    public void sendSms(String message,String[] phoneNumber) {

        Intent smsIntent = new Intent(Intent.ACTION_VIEW);
        smsIntent.setData(Uri.parse("sms:"));
        smsIntent.putExtra("sms_body", message);
        smsIntent.putExtra("address", phoneNumber);
        startActivity(smsIntent);       
    }
}

This is the output that i'm getting on button click

This is my 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" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="This is my main activity, from here, I want to display a dialog, 
                        after the user clicked the button below this text." />

    <Button
        android:id="@+id/Button01main"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show Dialog" />

</LinearLayout>

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

我不确定这是否适合您的情况，但如果您想将其设置为全宽或类似的东西，您需要获取活动的当前窗口并设置它的布局参数，如下所示：

myDialog.show();
Window window = myDialog.getWindow();
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);

编辑

FILL_PARENT已弃用，请改用

window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

您只需将样式“Theme_AppCompat_Light_Dialog_Alert”添加到您的对话框中，如下所示：

Dialog dialog = new Dialog(context, R.style.Theme_AppCompat_Light_Dialog_Alert);

你的对话框看起来像普通的警报对话框

我通过使用此代码删除标题栏解决了这个问题

    getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);

并为我的布局中的元素添加填充以根据我的喜好拉伸对话框。

好吧，我无法解决这个问题，但我发现搁浅了：创建一个 RelaytiveLayout 环绕您的根布局并将重力设置为中心，如下所示：

<RelativeLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:gravity="center">
    
   <YourRootLayoutHere/>

</RelativeLayout

Dialog class :- 

dialog = new Dialog(mContext);
dialog.setContentView(R.layout.dialog_feedback);
dialog.show();

使用 Relative_Layout 而不是 Linear_layout 来获得自定义对话框的全宽。我不知道为什么，但这对我有用。

    private void showdialog() {
    final Dialog dialog = new Dialog(this);
    dialog.setContentView(R.layout.activity_disclaimer);
    dialog.show();
    Window window = dialog.getWindow();
    window.setLayout(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
    Button dialogButton = (Button) dialog.findViewById(R.id.ok);
    dialogcb= (CheckBox) dialog.findViewById(R.id.checkBox);
    dialogButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            accepted = dialogcb.isChecked();
            SharedPreferences.Editor edit=prefs.edit();
            edit.putBoolean("show_again",!accepted);
            edit.commit();
            dialog.dismiss();
        }
    });

    dialog.show();
}
