要设置自定义布局的背景与ImageView的为透明

问题描述

我使用的是Android开发者文档建立一个自定义对话框，为了这个，我做了一个布局文件

I am building a Custom dialog box using the Android Developer docs link , for this i made a layout file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rotatelayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#80000000"
>

<ImageView
    android:id="@+id/dialogimage"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    />
</LinearLayout>

and i am inflating this dialog,

AlertDialog dialog;
AlertDialog.Builder builder;
builder = new AlertDialog.Builder(TabsActivity.this);
LayoutInflater inflator = (LayoutInflater)   getSystemService(LAYOUT_INFLATER_SERVICE);

ImageView image = (ImageView) view.findViewById(R.id.dialogimage);
image.setOnClickListener(new RotateLockListener());
image.setBackgroundColor(Color.parseColor("#80000000"));
if(locked)
{
    image.setImageResource(R.drawable.lock_icon);
}
else
{
    image.setImageResource(R.drawable.unlock_icon);
}
builder.setView(view).setCancelable(true);
dialog = builder.create();

推荐答案

或者你可以使用Dialog类此，

Or you can use Dialog class for this,

Dialog dialog = new Dialog(this,
                android.R.style.Theme_Translucent_NoTitleBar);
        Window window = dialog.getWindow();
        window.setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
                WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        window.setLayout(ViewGroup.LayoutParams.FILL_PARENT,
                ViewGroup.LayoutParams.FILL_PARENT);
        dialog.setCancelable(true);

        dialog.setCanceledOnTouchOutside(true);
        dialog.setContentView(R.layout.temp);
        dialog.show();
