在一些项目中，比如搜索，广告热门关键词等等都会用到下面这种效果的排版，如下图：
其实最通用的实现方案是自定义一个ViewGroup，然后自己计算布局。但是这种方式对于一些对自定义控件不太熟悉的人来说，有些难度，这里有一个通过拼凑的方法实现这种效果，下面是源代码，偷懒了一下，不想封装了，直接就写在一个Activity里面，谁有需要，自己去优化：
import android.app.Activity;import android.graphics.Paint;import android.os.Bundle;import android.view.LayoutInflater;import android.view.ViewGroup;import android.view.ViewGroup.LayoutParams;import android.widget.LinearLayout;import android.widget.TextView;public class TextViewItemActivity extends Activity {private boolean isFristTime = true;/** 标签之间的间距 px */final int itemMargins = 50;/** 标签的行间距 px */final int lineMargins = 50;private ViewGroup container = null;private String[] tags = { "大约在冬季", "漂洋过海的来看你", "天下有情人", "我很认真", "夜夜夜夜", "想你的夜", "背叛", "趁早", "旧情绵绵", "谁明浪子心", "安妮","说谎的爱人", "不浪漫的罪名", "不愿一个人", "风吹麦浪" };@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.textview_layout);container = (ViewGroup) findViewById(R.id.container);}@Overridepublic void onWindowFocusChanged(boolean hasFocus) {super.onWindowFocusChanged(hasFocus);if (hasFocus && isFristTime) {isFristTime = false;final int containerWidth = container.getMeasuredWidth() – container.getPaddingRight()- container.getPaddingLeft();final LayoutInflater inflater = getLayoutInflater();/** 用来测量字符的宽度 */final Paint paint = new Paint();final TextView textView = (TextView) inflater.inflate(R.layout.item_textview, null);final int itemPadding = textView.getCompoundPaddingLeft() + textView.getCompoundPaddingRight();final LinearLayout.LayoutParams tvParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);tvParams.setMargins(0, 0, itemMargins, 0);paint.setTextSize(textView.getTextSize());LinearLayout layout = new LinearLayout(this);layout.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));layout.setOrientation(LinearLayout.HORIZONTAL);container.addView(layout);final LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);params.setMargins(0, lineMargins, 0, 0);/** 一行剩下的空间 **/int remainWidth = containerWidth;for (int i = 0; i < tags.length; ++i) {final String text = tags[i];final float itemWidth = paint.measureText(text) + itemPadding;if (remainWidth > itemWidth) {addItemView(inflater, layout, tvParams, text);} else {resetTextViewMarginsRight(layout);layout = new LinearLayout(this);layout.setLayoutParams(params);layout.setOrientation(LinearLayout.HORIZONTAL);/** 将前面那一个textview加入新的一行 */addItemView(inflater, layout, tvParams, text);container.addView(layout);remainWidth = containerWidth;}remainWidth = (int) (remainWidth – itemWidth + 0.5f) – itemMargins;}resetTextViewMarginsRight(layout);}}/***************** 将每行最后一个textview的MarginsRight去掉 *********************************/private void resetTextViewMarginsRight(ViewGroup viewGroup) {final TextView tempTextView = (TextView) viewGroup.getChildAt(viewGroup.getChildCount() – 1);tempTextView.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));}private void addItemView(LayoutInflater inflater, ViewGroup viewGroup, LayoutParams params, String text) {final TextView tvItem = (TextView) inflater.inflate(R.layout.item_textview, null);tvItem.setText(text);viewGroup.addView(tvItem, params);}}Activity的Layout文件<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android=""android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical" ><TextViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:background="@android:color/darker_gray"android:gravity="center_horizontal"android:paddingBottom="5dp"android:paddingLeft="10dp"android:paddingRight="10dp"android:paddingTop="5dp"android:text="这只是一个demo而已"android:textSize="16sp" ></TextView><LinearLayoutandroid:id="@+id/container"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_marginTop="50dp"android:background="#8864dd"android:orientation="vertical"android:paddingBottom="10dp"android:paddingLeft="10dp"android:paddingRight="10dp"android:paddingTop="10dp" ></LinearLayout></LinearLayout>

也只有懂的接受自己的失败，才能更好的去发挥自身优势，也才能够更好的去实现自我
