Android的LinerLayout动态添加(addView)布局文件，不起效果？？

Question

package tech.together.Character.Components;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;

import java.util.List;

import tech.together.R;

/**

  public class BecomeEmployeeSkills extends LinearLayout implements View.OnClickListener {

  private LinearLayout skills;

  //private LayoutParams param = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

  private LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

  private List editSkillsViews;

  public BecomeEmployeeSkills(Context context) {
  super(context);
  initView(context);
  }

  public BecomeEmployeeSkills(Context context, AttributeSet attrs) {
  super(context, attrs);
  initView(context);
  }

  private void initView(Context context) {
  View.inflate(context, R.layout.layout_become_employee_skills, this);

  findViewById(R.id.add).setOnClickListener(this);
  findViewById(R.id.submit).setOnClickListener(this);
  skills = (LinearLayout) findViewById(R.id.skills);
  

  }

  @Override
  public void onClick(View v) {
  switch (v.getId()) {
  case R.id.add:
  //TODO 使用EditSkillView
  Log.d("URL", "onClick()ADD");

View view2 = (LinearLayout) LayoutInflater.from(getContext()).inflate(R.layout.view_edit_skill, skills, false);
view2.setLayoutParams(param);
skills.addView(view2);

            invalidate();
            skills.requestLayout();
            break;
        case R.id.submit:
            //TODO


            break;
    }
}

}

addView后用手机测试，点击按钮没有反应，也不报错，然后输出的是下面的log
06-07 09:47:39.350 8325-8325/tech.together D/URL: onClick()ADD
06-07 09:47:39.366 8325-8325/tech.together D/ColorDrawable: Color = -1118482, canvas = android.view.GLES20RecordingCanvas@2d50567e, mTintMode = SRC_IN, mTint = null, ColorDrawable = android.graphics.drawable.ColorDrawable@3e3c5c62
06-07 09:47:39.544 8325-8325/tech.together V/SettingsInterface: from settings cache , name = sound_effects_enabled , value = 0
0

真不知道是为什么原因，求解释！
