Android 方向更改时带有listview的自定义对话框(横向模式)

Android 方向更改时带有listview的自定义对话框(横向模式),android,dialog,screen-orientation,customdialog,Android,Dialog,Screen Orientation,Customdialog,我希望我的自定义对话框可以在纵向和横向模式下工作。为此,我找到了一个在layoutland文件夹中创建XML的解决方案。因此,我复制了布局并将其粘贴到layout land文件夹中,并对添加的滚动视图进行了修改。不过,它并没有像我预期的那样起作用。尽管添加了scrollview,该对话框仍不能完全滚动 该对话框还包含一个列表视图 我的布局land/dialog.xml如下所示 <android.support.constraint.ConstraintLayout xmlns:andro

我希望我的自定义对话框可以在纵向和横向模式下工作。为此,我找到了一个在layoutland文件夹中创建XML的解决方案。因此,我复制了布局并将其粘贴到layout land文件夹中,并对添加的滚动视图进行了修改。不过,它并没有像我预期的那样起作用。尽管添加了scrollview,该对话框仍不能完全滚动

该对话框还包含一个列表视图

对话框在纵向模式下的外观与。 对话框在横向模式下的外观

我的VeriDocDialog.java代码如下

public class VeriDocDialog extends Dialog {
     private View dialogView;

    public VeriDocDialog(@NonNull Context context, String dialogType, int iconDrawableId, String instructions,String bottomText, List<Contact> contactList, String buttonText) {

        super(context);
        this.context = context;
        this.dialogType = dialogType;
        this.iconDrawableId = iconDrawableId;
        this.instruction = instructions;
        this.buttonText = buttonText;
        this.contactList = contactList;
        this.bottomText = bottomText;

        setupVeriDocDialog();
    }

    public VeriDocDialog(@NonNull Context context, String dialogType, int iconDrawableId, String instructions, String bottomText, List<ResolveInfo> shareList, String buttonText, Intent shareIntent) {

        super(context);
        this.context = context;
        this.dialogType = dialogType;
        this.iconDrawableId = iconDrawableId;
        this.instruction = instructions;
        this.buttonText = buttonText;
        this.shareList = shareList;
        this.bottomText = bottomText;
        this.shareIntent = shareIntent;

        setupVeriDocDialog();
    }

    private void setupVeriDocDialog() {

        if (getWindow() != null) {
            getWindow().setBackgroundDrawableResource (R.color.transparent);
            getWindow().setGravity(Gravity.CENTER);
            getWindow().getAttributes().windowAnimations = R.style.dialogAnimation;
            requestWindowFeature(Window.FEATURE_NO_TITLE);
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

         dialogView = getLayoutInflater().inflate(R.layout.dialog_veri_doc, null);
         setContentView(dialogView);

         bindView();
         initialise(dialogType);
     }

     //.... and other methods .....
}    
如何从活动中调用此对话框:

private void displayInviteDialog() {
    contactList = new ArrayList<>();

    inviteDialog = new VeriDocDialog(ScratchAndWinActivity.this,
            VeriDocDialog.TYPE_INVITE,
            R.drawable.invite_32,
            getString(R.string.str_invite_instruction),
            getString(R.string.str_equation_invite),
            contactList, VeriDocDialog.TYPE_INVITE);


    inviteDialog.show();
}
问题是,布局不合适。我也提到了land文件夹中的xml布局,并将视图放在scrollview中,但scrollview仍然不会将对话框滚动到底

是因为listview吗?如果是,请提供一些解决方案。如果不是,原因是什么?如何克服这种情况?任何帮助都将不胜感激

当我尝试在方向为横向时打开对话框时,land文件夹中的xml膨胀了。但是,当我在纵向打开对话框之后,我改变了方向,xml在常规布局中是相同的,而不是来自land文件夹

请帮我解决这个问题

在VeriDocDialog类中,转到方法

private void setupVeriDocDialog() {
    if (getWindow() != null) {
        getWindow().setBackgroundDrawableResource (R.color.transparent);
        getWindow().setGravity(Gravity.CENTER);
        getWindow().getAttributes().windowAnimations = R.style.dialogAnimation;
        getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT); // Add this line and change your height & width acc.
        //Moreover you can add margin to dialog from all directions.
        requestWindowFeature(Window.FEATURE_NO_TITLE);
    }
}
这将帮助您在横向模式下显示对话框,而无需任何剪辑

要将页边距更改为对话框

供参考


在我的布局\activity\u main.xml中,使用

<ScrollView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:id="@+id/scrollView"
        android:visibility="visible">
....
</ScrollView>
在land\activity\u main.xml中

<HorizontalScrollView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:id="@+id/scrollView"
        android:visibility="visible">
....
</HorizontalScrollView>
我希望这对你有帮助

这是因为您的对话框在屏幕方向更改后不会重新创建。它有着古老的资源布局

对于解决方案,您可以检测方向更改并重新创建对话框(如果已打开)。 您可以在活动中使用OnConfiguration Changed来检测方向更改

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
    }

    if (inviteDialog !=null && inviteDialog.isShowing()){
        inviteDialog .dismiss(); 
        displayInviteDialog();
    }
}

private void displayInviteDialog() {
    contactList = new ArrayList<>();

    inviteDialog = new VeriDocDialog(ScratchAndWinActivity.this,
            VeriDocDialog.TYPE_INVITE,
            R.drawable.invite_32,
            getString(R.string.str_invite_instruction),
            getString(R.string.str_equation_invite),
            contactList, VeriDocDialog.TYPE_INVITE);


    inviteDialog.show();
}
2> 还可以通过编程方式设置对话框的高度和宽度匹配。看

更新

使用NestedScrollView而不是ScrollView,因为ListView本身具有滚动属性,这将导致冲突

更新

我创建了一个示例,它在这两种模式下都工作得很好,您会惊讶地发现我没有为dialog设置任何特殊属性以使其工作。这是样品

import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.Window;
import android.view.WindowManager;
import android.widget.ArrayAdapter;
import android.widget.ListView;

import com.innovanathinklabs.sample.R;

/**

public class ListActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        MyDialog dialog = new MyDialog(this);
        dialog.show();
        Window window = dialog.getWindow();
        window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
    }

    public static class MyDialog extends Dialog {
        String[] mobileArray = {
                "Android", "IPhone", "WindowsMobile", "Blackberry",
                "WebOS", "Ubuntu", "Windows7", "Max OS X", "Android", "IPhone", "WindowsMobile", "Blackberry",
                "WebOS", "Ubuntu", "Windows7", "Max OS X", "Android", "IPhone", "WindowsMobile", "Blackberry",
                "WebOS", "Ubuntu", "Windows7", "Max OS X",
        };

        public MyDialog(@NonNull Context context) {
            super(context);
        }

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.dialog_sample);
            ArrayAdapter adapter = new ArrayAdapter<>(getContext(),
                    R.layout.row_list, mobileArray);
            ListView listView = findViewById(R.id.listView);
            listView.setAdapter(adapter);
        }
    }
}
和dialog_sample.xml

这是输出

请注意。 我没有去处理方向,它的工作如预期。 我重视孩子的观点。因此,它会自动适应两个方向。 xml布局中的问题是您并没有使用权重/百分比,所以内容超出了屏幕。
如何设置边距?尝试对所有参数(如高度、宽度等)使用一次所有硬编码值并检查结果,我在将约束布局用作对话框视图的根时遇到问题。静态值如layoutParams.x=10,这里的10是静态值,可以是您想要的任何内容@Riddhisame,与前面的一样,没有任何变化,没有结果!:你能发布问题的截图吗?@RahulKhurana我已经发布了。请阅读问题。我提到了链接。对话框在纵向模式下的外观参见此处,而在横向模式下的外观参见此行。请检查。您从下面得到答案了吗?@RahulKhurana没有。还没有。还有一个问题:您是否实现了OnConfiguration Changed方法?试着重新打开没有帮助的对话:经过几天的努力终于打开了。我的问题解决了。问题是滚动视图。在我的XML中,我没有将XML应用于整个视图。在将scrollview应用于整个XML之后,问题就解决了。这可能是一种方法,但是如果您只希望列表滚动,那么可以使用权重。顺便说一句,我以为你已经尝试了整个scrollView。还要删除处理方向配置更改的代码,这是没有用的。不,不,我使用的是该代码。这是有用的。因为我有两个文件。一个用于纵向,一个用于横向。您只能通过纵向xml来实现这一点。正如我在示例中所示。也可以在纵向模式下使用滚动视图。它也将在横向模式下工作。
