dialogfragment 的使用

public class DialogTest extends DialogFragment {

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.sdf, null);
builder.setView(view)
// Add action buttons
.setPositiveButton("登录",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
}
}).setNegativeButton("取消", null);
Dialog dialog = builder.create();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);//不显示标题
return dialog;
}
}

DialogTest dialogTest = new DialogTest();
dialogTest.show(getSupportFragmentManager(),"dialog");

public class DialogTest extends DialogFragment {

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉dialog的标题栏
return inflater.inflate(R.layout.sdf,container,false);
}

}
