在我的活动中:
@Override
public void showProgressDialog() {
dialogFragment = new ProgressDialogFragment();
dialogFragment.setCancelable(false);
dialogFragment.show(getSupportFragmentManager(), "tag");
}
这是我的对话框片段
import android.support.v4.app.DialogFragment;
public class ProgressDialogFragment extends DialogFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.progress_dialog_fragment, null);
}
此处xml:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="64dp">
<ProgressBar
android:id="@+id/progressBar"
style="?android:attr/progressBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="@dimen/margin_default"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/titleTextView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="@dimen/margin_default"
android:text="@string/awaiting_client_confirmation"
android:textColor="@android:color/black"
android:textSize="17sp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="@+id/progressBar"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
}
结果如下:
您可以看到它在整个屏幕上显示。但我为此设置了高度:
android:layout_height="64dp"
我想显示 64dp 的高度。
也不会显示titleTextView
