我正在尝试创建一个显示DatePicker的自定义对话框,但该元素会在视图右侧添加额外的边距/填充。这种情况仅发生在Android 7.1.1,Nexus 6P上,但在其他低分辨率手机上运行得非常好。如何删除额外的填充? 我的XML布局代码:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<DatePicker
android:id="@+id/date_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:endYear="2012"
android:startYear="1930" />
</LinearLayout>
编辑:添加了我的Java代码:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_attributes);
assert getSupportActionBar() != null;
getSupportActionBar().setTitle("Register");
final TextView birthDateSelectedTextView = (TextView) findViewById(R.id.text_view_birth_date);
Button dialogOpenButton = (Button) findViewById(R.id.button_dialog_date_picker);
dialogOpenButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final Dialog dialog = new Dialog(UserAttributesActivity.this);
final AlertDialog.Builder builder = new AlertDialog.Builder(UserAttributesActivity.this);
LayoutInflater inflater = getLayoutInflater();
View dialogView = inflater.inflate(R.layout.dialog_date_picker, null);
builder.setView(dialogView);
final DatePicker datePicker = (DatePicker) dialogView.findViewById(R.id.date_picker);
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
day = datePicker.getDayOfMonth();
month = datePicker.getMonth() + 1;
year = datePicker.getYear();
String date = "" + day + "/" + month + "/" + year;
birthDateSelectedTextView.setText(date);
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.show();
}
});
}

使用AlertDialog.Builder
添加样式,如下所示。
AlertDialog.Builder builder = new AlertDialog.Builder(UserAttributesActivity.this, android.R.style.Theme_DeviceDefault_Light_Dialog_NoActionBar);

@Ankita是对的,但是如果你正在使用AppCompat,那么事情会更复杂:
定义新样式并扩展AppCompat的Light.Dialog
样式
<style name="DatePickerDialogStyle" parent="@style/Theme.AppCompat.Light.Dialog">
...
</style>
然后添加属性以模仿NoActionBar
部分:
<style name="DatePickerDialogStyle" parent="@style/Theme.AppCompat.Light.Dialog">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
最后,既然你不再从你的AppTheme
获取app compat颜色,请将它们复制到你的新主题:
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">@color/primary</item>
<item name="colorPrimaryDark">@color/primary_dark</item>
<item name="colorAccent">@color/accent</item>
</style>
<style name="DatePickerDialogStyle" parent="@style/Theme.AppCompat.Light.Dialog">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="colorPrimary">@color/primary<item>
<item name="colorPrimaryDark">@color/primary_darkitem>
<item name="colorAccent">@color/accent</item>
</style>
然后应用这个新主题:
AlertDialog.Builder builder
= new AlertDialog.Builder(UserAttributesActivity.this,
DatePickerDialogStyle);

使用此
DatePickerDialog.Builder builder = null;
// 5.0+ 需要更换主题以去除右侧白边
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
builder = new DatePickerDialog.Builder(this.getActivity(),
android.R.style.Theme_DeviceDefault_Light_Dialog_NoActionBar);
}
// 4.4 不需要,相反加上会有白边
else {
builder = new DatePickerDialog.Builder(this.getActivity());
}

如果您使用的是类似androidx.fragment.app.DialogFragment()的类。这样做:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// Set the dialog style.
setStyle(STYLE_NO_TITLE, android.R.style.Theme_DeviceDefault_Light_Dialog_NoActionBar)
}
