Question

我正在开发一个Android聊天消息。我有一个包含imageview的活动。点击imageview，将打开一个对话框。对话框的布局是：

emoji.xml

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

    <FrameLayout
        android:id="@+id/emojicon"
        android:layout_width="match_parent"
        android:layout_height="50dp" />

</LinearLayout>

处理图片的代码点击

 imageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            hideKeyboard();  // hiding the keyboard
           // showEmojiPopUp(!showEmoji);
            Dialog dialog = new Dialog(ChatActivity.this);
            dialog.setContentView(R.layout.emoji);
            getSupportFragmentManager().beginTransaction().replace(R.id.emojicon, EmojiconsFragment.newInstance(false)).commit();
            dialog.show();
        }
    });

在单击图像视图时，我正在创建一个包含FrameLayout的对话框.Here EmojiFragment将创建一个表情符号面板，emoji.xml中的FrameLayout将被EmojiFragment替换。但是在这里我得到了下面提到的错误：

java.lang.IllegalArgumentException: No view found for id 0x7f0c004b (com.almabay.almachat:id/emojicon) for fragment EmojiconsFragment{429a7f68 #1 id=0x7f0c004b}

请帮我解决。

这是显示自定义对话的示例。自定义是xml布局

final Dialog dialog = new Dialog(context);
            dialog.setContentView(R.layout.custom);
            dialog.setTitle("Title...");

            // set the custom dialog components - text, image and button
            TextView text = (TextView) dialog.findViewById(R.id.text);
            text.setText("Android custom dialog example!");
            ImageView image = (ImageView) dialog.findViewById(R.id.image);
            image.setImageResource(R.drawable.ic_launcher);

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

            dialog.show();
          }

我希望这会有所帮助。
