android– 以编程方式创建LinearLayout中的元素

概述我正在运行时创建一个LinearLayout,我在其中添加了两个元素：textview和一个微调器.我想将它们水平居中在LinearLayout中,但无法弄清楚如何做到这一点.下面是我用来创建视图的代码：LinearLayoutleftSideAttributLayout=newLinearLayout(this);leftSideAttributLayout.setOrie

我正在运行时创建一个linearLayout,我在其中添加了两个元素：textvIEw和一个微调器.
我想将它们水平居中在linearLayout中,但无法弄清楚如何做到这一点.下面是我用来创建视图的代码：

linearLayout leftSIDeAttributLayout = new linearLayout(this);leftSIDeAttributLayout.setorIEntation(linearLayout.HORIZONTAL);linearLayout.LayoutParams attributLayoutParams = new linearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);leftSIDeAttributLayout.setLayoutParams(attributLayoutParams);linearLayout.LayoutParams leftLabelParams = new linearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);leftLabelParams.gravity = Gravity.CENTER;leftAttributLabel.setLayoutParams(leftLabelParams);         TextVIEw leftAttributLabel = new TextVIEw(this);leftAttributLabel.setText(attribut.getNom());leftAttributLabel.setTextcolor(color.WHITE);Tools.applyFont(getApplicationContext(), leftAttributLabel, "gothic_0.TTF");linearLayout.LayoutParams spinnerParams = new linearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);  spinnerParams.gravity = Gravity.CENTER_HORIZONTAL;spinnerParams.setmargins(10, 0, 0, 0);Spinner leftAttributValues = new Spinner(this);leftAttributValues.setLayoutParams(spinnerParams);leftAttributValues.setAdapter(adapter);leftAttributValues.setBackgroundResource(R.drawable.lenti_attributspinner);leftAttributValues.setTag(attribut);

如果有人可以帮助我,那会很棒！谢谢 ：)

解决方法:

因为您必须将重力设置为线性布局,所以只需在设置线性布局参数后放置此线

leftSIDeAttributLayout.setGravity(Gravity.CENTER);

这是您的代码中的示例

 linearLayout leftSIDeAttributLayout = new linearLayout(this);            leftSIDeAttributLayout.setorIEntation(linearLayout.HORIZONTAL);            linearLayout.LayoutParams attributLayoutParams = new linearLayout.LayoutParams(linearLayout.LayoutParams.MATCH_PARENT, linearLayout.LayoutParams.WRAP_CONTENT);            attributLayoutParams.gravity = Gravity.CENTER;            leftSIDeAttributLayout.setLayoutParams(attributLayoutParams);            leftSIDeAttributLayout.setGravity(Gravity.CENTER);            linearLayout.LayoutParams leftLabelParams = new linearLayout.LayoutParams(linearLayout.LayoutParams.WRAP_CONTENT, linearLayout.LayoutParams.WRAP_CONTENT);            //leftLabelParams.gravity = Gravity.CENTER;            TextVIEw leftAttributLabel = new TextVIEw(this);            leftAttributLabel.setText("sample");            leftAttributLabel.setTextSize(25);            leftAttributLabel.setLayoutParams(leftLabelParams);            linearLayout.LayoutParams spinnerParams = new linearLayout.LayoutParams(linearLayout.LayoutParams.WRAP_CONTENT,linearLayout.LayoutParams.WRAP_CONTENT);           // spinnerParams.gravity = Gravity.CENTER;            spinnerParams.setmargins(10, 0, 0, 0);            Spinner leftAttributValues = new Spinner(this);            leftAttributValues.setLayoutParams(spinnerParams);            leftSIDeAttributLayout.addVIEw(leftAttributLabel);            leftSIDeAttributLayout.addVIEw(leftAttributValues);            mainvIEw.addVIEw(leftSIDeAttributLayout);
