DialogFragment阴影

Question

​

​

我想要隐藏我的对话片段

我们在对话框中使用以下代码-

        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(root);
        if (dialog.getWindow() != null) {
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
            dialog.getWindow().setLayout(
                    ViewGroup.LayoutParams.MATCH_PARENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
        }```

Answer 1

public class FullSizeImageDialog extends Dialog {
private ImageView imageView;
private ProgressBar fullImageProgreesBar;
private Context dialogContext;

public FullSizeImageDialog(@NonNull Context context) {
    super(context);
    setContentView(R.layout.full_size_image_dialog);
    dialogContext = context;
    imageView = findViewById(R.id.full_size_image);
    fullImageProgreesBar = findViewById(R.id.fullImageProgreesBar);
    }
}

，这是对话框的布局(在我的例子中是R.id.full_size_image)：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent">


 <!--Place your views here-->


 </android.support.constraint.ConstraintLayout>

现在剩下的就是要么使用卡片视图，要么检查this thread，谈论视图上的阴影。

当你想要显示你的对话框时，是非常简单的：

FullSizeImageDialog dialog = new FullSizeImageDialog ();
dialog.show();
