Android中如何實現一個時間軸效果

本文小編為大家詳細介紹“Android中如何實現一個時間軸效果”，內容詳細，步驟清晰，細節處理妥當，希望這篇“Android中如何實現一個時間軸效果”文章能幫助大家解決疑惑，下面跟著小編的思路慢慢深入，一起來學習新知識吧。

其實只不過是布局+動態生產TextView罷了，一開始選的是 FrameLayout，后來發現在處理單擊事件的時候一個問題  ，例如：

FrameLayout frameLayout= (FrameLayout) findViewById(R.id.frameLayout);     for(...){         frameLayout.add(tv1);        frameLayout.add(tv2);        //在這里直接處理單擊事件肯定是不行的，tv1和tv2是重合在一起的     }                 FrameLayout frameLayout= (FrameLayout) findViewById(R.id.frameLayout);     for(...){         tv1.setLayoutparams(....);        frameLayout.add(tv1);        frameLayout.add(tv2);       //在這里直接處理單擊事件就可以了，不知道為什么？     }

所以，直接改 成Linearlayout了，改成Linearlayout后，那些TextView的位置也好設置多了，下面是代碼：

package com.lliq.ui;    import android.app.Activity;       import android.os.Bundle;       import android.util.Log;       import android.view.View;       import android.view.View.OnClickListener;      import android.view.Window;       import android.widget.FrameLayout;       import android.widget.LinearLayout;       import android.widget.TextView;             import com.lliq.R;             public class HistoryActivity extends Activity      {          private final int space_year = 5;           private final int space_month = 5;          private String[] year = { "2010", "2011", "2012", "2013" };          private String[][] month = { { "01", "03", "04", "11" }, { "07" }, { "01", "03", "04", "11" },                  { "07" } };                  boolean menu_falg = false;// 單擊改變菜單圖標                  private TextView[] tv_year;          private TextView[] tv_month;           private TextView content;                   @Override          protected void onCreate(Bundle savedInstanceState)           {              super.onCreate(savedInstanceState);              requestWindowFeature(Window.FEATURE_NO_TITLE);               setContentView(R.layout.iq_history);              initLayout();          }                private void initLayout()          {               LinearLayout btnback = (LinearLayout) findViewById(R.id.history_layouthome);               final TextView btnhome = (TextView) findViewById(R.id.history_btnhome);              btnback.setOnClickListener(new OnClickListener()             {                 @Override                 public void onClick(View arg0)                  {                      menu_falg = !menu_falg;                     btnhome.setBackgroundResource(menu_falg ? R.drawable.menuspread : R.drawable.menu_n);                     MainActivity.handler.sendEmptyMessage(0);                  }              });                     content = (TextView) findViewById(R.id.content);              LinearLayout timelayout = (LinearLayout) findViewById(R.id.timelayout);              tv_year = new TextView[year.length];              for (int i = 0; i < year.length; i++)              {                  tv_year[i] = new TextView(this);                  tv_year[i].setPadding(                        10,                          i == 0 ? space_year : space_year                                  * (13 - Integer.parseInt(month[i - 1][month[i - 1].length - 1])), 0, 0);                   tv_year[i].getPaint().setFakeBoldText(true);                 tv_year[i].setTextSize(14);                  tv_year[i].setTag(year[i]);                   tv_year[i].setText(year[i] + "  --");                  tv_year[i].setOnClickListener(new TimeLineClickListener(tv_year[i]));                   timelayout.addView(tv_year[i]);                  tv_month = new TextView[year.length];                  for (int j = 0; j < month[i].length; j++)                  {                      tv_month[i] = new TextView(this);                      if (j == 0)                      {                          tv_month[i].setPadding(20, space_month * Integer.parseInt(month[i][j]), 0, 0);                       } else                     {                          tv_month[i].setPadding(20, space_month                                   * (Integer.parseInt(month[i][j]) - Integer.parseInt(month[i][j - 1])),                                  0, 0);                      }                       tv_month[i].setTextSize(12);                       tv_month[i].setText(month[i][j] + "月   --");                      tv_month[i].setTag(year[i] + "-" + month[i][j]);                       tv_month[i].setOnClickListener(new TimeLineClickListener(tv_month[i]));                     timelayout.addView(tv_month[i]);                  }              }                 }                 class TimeLineClickListener implements OnClickListener           {                     TimeLineClickListener(View v)               {             }                     @Override              public void onClick(View v)               {                   content.setText(v.getTag().toString());              }          }              }
