我有一个对话片段,看起来像那样。
AlertDialog ad = builder.create();
Drawable d = new ColorDrawable(Color.BLACK);
d.setAlpha(130);
ad.getWindow().setBackgroundDrawable(d);
此代码获得半透明背景。但我仍然在底部有一个白色的部分。我想摆脱白色只是半透明背景
我已经尝试了很多我在其他帖子中看到过的东西。
我不知道在DialogFragment,AlertDialog和LinearLayout之间必须更改的对象是什么。
它可能不是LinearLayout,因为当我增加保证金时,没有任何动静。
这是我的代码:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// setStyle(DialogFragment.STYLE_NORMAL, 0);
// setStyle(STYLE_NO_FRAME, R.style.CustomDialog);
// setStyle(STYLE_NO_FRAME, 0);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
View view = getActivity().getLayoutInflater().inflate(
R.layout.share_or_die, null);
AlertDialog ad = builder.create();
Drawable d = new ColorDrawable(Color.BLACK);
d.setAlpha(130);
ad.getWindow().setBackgroundDrawable(d);
ad.setCanceledOnTouchOutside(true);
ad.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
ad.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
return ad;
}
当用户点击后退按钮时,我只需在mainActivity中调用它:
@Override
public void onBackPressed() {
if (isUserConnected && !hasShared) {
shareOnExitDialog = new ShareOnExitDialog();
shareOnExitDialog.setCancelable(true);
shareOnExitDialog.show(getSupportFragmentManager(), "Exit");
} else {
finish();
}
}
任何帮助将不胜感激!

问题出在默认对话框主题中。根据{{3}}和this答案,您可以更轻松地实现目标。
活动应如下所示:
public class MyActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
}
@Override
public void onBackPressed() {
MyDialogFragment.newInstance("title title").show(getSupportFragmentManager(), "dialog");
}
}
片段:
public class MyDialogFragment extends android.support.v4.app.DialogFragment {
/**
* Create a new instance of MyDialogFragment, providing "title"
* as an argument.
*/
static MyDialogFragment newInstance(String title) {
MyDialogFragment frag = new MyDialogFragment();
Bundle args = new Bundle();
args.putString("title", title);
frag.setArguments(args);
return frag;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = new Dialog(getActivity(),android.R.style.Theme_Translucent_NoTitleBar);
final View view = getActivity().getLayoutInflater().inflate(R.layout.share_or_die, null);
final Drawable d = new ColorDrawable(Color.BLACK);
d.setAlpha(130);
dialog.getWindow().setBackgroundDrawable(d);
dialog.getWindow().setContentView(view);
final WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
params.width = WindowManager.LayoutParams.WRAP_CONTENT;
params.height = WindowManager.LayoutParams.WRAP_CONTENT;
params.gravity = Gravity.CENTER;
dialog.setCanceledOnTouchOutside(true);
return dialog;
}
}
另外,请务必执行以下操作:在活动setContentView()
之前,应添加getWindow().requestFeature(Window.FEATURE_NO_TITLE)
以使用*NoTitleBar
样式。
结果是(我使用了LinearLayout
并且单个TextView
):

我希望它可以帮到你
@Override
public void onStart() {
super.onStart();
Window window = getDialog().getWindow();
WindowManager.LayoutParams windowParams = window.getAttributes();
windowParams.dimAmount = 0.0f;
window.setAttributes(windowParams);
}

以上解决方案均不适合我。我发现工作的是确保我导入了android.support.v7.app.AlertDialog而不是通用的app.alertdialog。
希望这也有助于其他人。
