Question

字体大小已更改，但另一个视图未移动。我不能在这个布局中添加任何元素。我只能修改现有视图，例如我可以更改颜色或文本，但viewHolder.layout.addView(textView)不做任何事情。为什么view大小不会改变？

public class StackAdapter extends BaseAdapter...
...
public View getView...
final ViewHolder viewHolder;
...
viewHolder.layout = (LinearLayout) convertView.findViewById(R.id.telephone_1);
...
    viewHolder.layout.post(new Runnable() {
                    @Override
                    public void run() {
                        TextView textView = (TextView)viewHolder.layout.findViewById(R.id.textView11);
                        textView.setText("din1");
                        textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 22);

    //or
                        TextView textView2 = (TextView)viewHolder.layout.findViewById(R.id.textView22);
                        textView2.setText("din2");
                        textView2.setTextSize(TypedValue.COMPLEX_UNIT_SP, 22);
                        int height_in_pixels2 = textView2.getLineCount() * textView2.getLineHeight(); //approx height text
                        textView2.setHeight(height_in_pixels2);

                    }
                });

Answer 1

这适用于我的项目

 textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, textView.getTextSize() + 3.0f);

并享受编码......

更改高度或宽度使用此....

  LinearLayout.LayoutParams linearPrams = new   LinearLayout.LayoutParams(LayoutParam.WRAP_CONTENT,LayoutParam.WRAP_CONTENT);

    textView.setLayoutParams(linearPrams);

PercentFrameLayout所有线性布局应以百分比方式......

<android.support.percent.PercentFrameLayout
         xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:app="http://schemas.android.com/apk/res-auto"
         android:layout_width="match_parent"
         android:layout_height="match_parent">
     <LinearLayout
         app:layout_widthPercent="50%"
         app:layout_heightPercent="50%"
         app:layout_marginTopPercent="25%"
         app:layout_marginLeftPercent="25%"/>
 </android.support.percent.PercentFrameLayout/>

无法更改TextView的大小
