安卓 : Dialog occupy 100% width

Question

 final Dialog dialog = new Dialog(this, R.style.theme_dialog);
 dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
 dialog.setContentView(R.layout.dialog_name);
 dialog.setCancelable(false);

 dialog.getWindow().setGravity(Gravity.TOP);
 dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

上面的代码占据了大约 90% 的宽度，但我想要 100%。

Answer 1

添加以下样式

<style name="Theme_Dialog" parent="android:Theme.Holo.Dialog">
        <item name="android:windowMinWidthMajor">100%</item>
        <item name="android:windowMinWidthMinor">100%</item>
</style> 

和

final Dialog dialog = new Dialog(getActivity(), R.style.Theme_Dialog);
