Make Android Activity looks like dialog
提问by Matroska
I am trying to open a dialog on widget click. I have solved the problem skinning the activity started on click with android:theme="@android:style/Theme.Dialog". Unfortunately I cannot reach the same look of a dialog.
我正在尝试在单击小部件时打开一个对话框。我已经解决了通过单击开始的活动皮肤的问题android:theme="@android:style/Theme.Dialog"。不幸的是，我无法达到对话框的相同外观。
This is the outcome:
这是结果：
Instead, I would like to reach this result (except for the button, of course):
相反，我想达到这个结果（当然按钮除外）：
(the widget dialog you can see keeping the screen pushed)
（您可以看到保持屏幕推送的小部件对话框）
As you can see there are some differences: the color of the list items, the color of the text and the list item separator. Is there a predefined theme/style to obtain the same look of a standard dialog? If not, what are the steps to follow to reach that result?
如您所见，存在一些差异：列表项的颜色、文本的颜色和列表项分隔符。是否有预定义的主题/样式来获得与标准对话框相同的外观？如果不是，要遵循哪些步骤才能达到该结果？
I have seen that the widget provided by FoxyRing has the behaviour I would like to have.
我已经看到 FoxyRing 提供的小部件具有我想要的行为。

Why not use a "traditional" Main Activity with a transparent background layout
为什么不使用具有透明背景布局的“传统”主要活动
and call a standard dialog from it ?
并从中调用标准对话框？
... well if I understood you correctly, that would make the trick in a very easy way, isn't it ?
……好吧，如果我理解正确的话，那会很容易搞定，不是吗？

you could dynamically create the dialog like this:
您可以像这样动态创建对话框：
Context mContext = this;
Dialog dialog = new Dialog(mContext);
dialog.setContentView(R.layout.data_dialog);
dialog.setTitle("Your title");
AlertDialog.Builder builder;
AlertDialog alertDialog;
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.data_dialog,
(ViewGroup) findViewById(R.id.AbsoluteLayout01));
builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
alertDialog = builder.create();
alertDialog.show();
final EditText txtUsername = (EditText) layout.findViewById(R.id.txtUsername);
final AlertDialog thisDialog = alertDialog;
Button btnSave = (Button) layout.findViewById(R.id.btnSave);
btnSave.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String strtxtUsername = txtUsername.getText().toString();
//do something...
}
});
To close the dialog, call thisDialog.dismiss();
要关闭对话框，请调用 thisDialog.dismiss();
The style looks like the regular Theme.Light.NoTitleBar with a ListView with an Icon and a Title-Text.
样式看起来像常规的 Theme.Light.NoTitleBar，带有一个带有图标和标题文本的 ListView。
Hope that helps!
希望有帮助！

There is actually a far simpler way to do this than what I suggested below.
Have a look at:
https://developer.android.com/guide/topics/ui/dialogs.htmlunder the headline "Adding a list".
实际上有一种比我在下面建议的方法更简单的方法。
看看：https:
//developer.android.com/guide/topics/ui/dialogs.html在标题“添加列表”下。
