###最近项目要开发一个新版本，发现项目中许多布局大致都相同改动不大，并且布局中代码量非常之多不好阅读，针对项目相关内容进行了封装。 ###实现思路： ####通过继承RelativeLayout实现动态添加所需要的控件，TextView ImageView View 一共封装了8个控件 leftImg reightImg leftTv rightTv centerTv leftTopTv leftBottomTv bottomLine 根据需要动态添加AddView(View) 通过LayoutParams.addRule()设置控件的位置，LayoutParams.setMargins()设置大小进行所需控件的控制实现以下效果：
//左边图片初始化
if (leftImgRes != null) {
initLeftImg();
}
private void initLeftImg() {
leftIV = new ImageView(mContext);
int width = leftImgWidht != 0 ? leftImgWidht : LayoutParams.WRAP_CONTENT;
int height = leftImgHeight != 0 ? leftImgHeight : LayoutParams.WRAP_CONTENT;
LayoutParams leftImgParams = new LayoutParams(width, height);
leftImgParams.addRule(ALIGN_PARENT_LEFT, TRUE);
leftImgParams.addRule(RelativeLayout.CENTER_VERTICAL, TRUE);
leftImgParams.setMargins(leftImgMarginleft, 0, 0, 0);
leftIV.setScaleType(ImageView.ScaleType.FIT_XY);
leftIV.setId(R.id.leftImg);
leftIV.setLayoutParams(leftImgParams);
leftIV.setImageDrawable(leftImgRes);
leftIV.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (OnTextViewClickListener != null) {
OnTextViewClickListener.OnLeftImgClick();
}
}
});
addView(leftIV);
}
####添加TextView
//左边文字初始化
if (!TextUtils.isEmpty(leftTvString)) {
initLeftTv();
}
private void initLeftTv() {
leftTv = new TextView(mContext);
LayoutParams leftTvParams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
leftTvParams.addRule(RelativeLayout.CENTER_VERTICAL, TRUE);
leftTvParams.addRule(RelativeLayout.RIGHT_OF, R.id.leftImg);
leftTvParams.setMargins(leftTvMarginleft, 0, 0, 0);
leftTv.setLayoutParams(leftTvParams);
leftTv.setTextColor(leftTvColor);
leftTv.setId(R.id.leftTv);
leftTv.setTextSize(TypedValue.COMPLEX_UNIT_PX, leftTvSize);
leftTv.setText(leftTvString);
addView(leftTv);
}
####代码中设置TextView的公共方法
//代码设置左边文字
public CustomTextView setLeftTv(String tvStr, String tvColor) {
leftTvString = TextUtils.isEmpty(tvStr) ? leftTvString : tvStr;
leftTvColor = TextUtils.isEmpty(tvColor) ? leftTvColor : Color.parseColor(tvColor);
if (leftTv == null) {
initLeftTv();
} else {
leftTv.setText(leftTvString);
leftTv.setTextColor(leftTvColor);
}
return this;
}
####只需搞懂这三个方法，你也可以根据自己的项目需求定义自己需要的组合控件 ####使用方法 #####xml(根据自己需要的属性自定义)
