Android 自定义表格显示数据

Android 自定义TextView控件，用来组成表格方便数据的展示。

首先看一下效果

样式不是很好看，需要用的可以自己优化一下。

实现方式很简单。

　　1、自定义控件 MyTableTextView 继承 TextView 重写onDraw方法。在里面添加话边框的操作。

 package lyf.com.mytableview;

 import android.content.Context;
 import android.graphics.Canvas;
 import android.graphics.Color;
 import android.graphics.Paint;
 import android.util.AttributeSet;
 import android.widget.TextView;

 /**
  * lyf on 2016/06/27
  * 自定义TextView
  */
 public class MyTableTextView extends TextView {

     Paint paint = new Paint();

     public MyTableTextView(Context context, AttributeSet attrs) {
         super(context, attrs);
         int color = Color.parseColor("#80b9f2");
         // 为边框设置颜色
         paint.setColor(color);
     }

     @Override
     protected void onDraw(Canvas canvas) {
         super.onDraw(canvas);
         // 画TextView的4个边
         canvas.drawLine(0, 0, this.getWidth() - 1, 0, paint);
         canvas.drawLine(0, 0, 0, this.getHeight() - 1, paint);
         canvas.drawLine(this.getWidth() - 1, 0, this.getWidth() - 1, this.getHeight() - 1, paint);
         canvas.drawLine(0, this.getHeight() - 1, this.getWidth() - 1, this.getHeight() - 1, paint);
     }
 }

　　2、主布局，什么也不用写。直接放一个LinearLayout就好。但因为表格的宽度和高度往往超过屏幕的宽高度，因此需要我们添加ScrollView 和HorizontalScrollView。为了让HorizontalScrollView填满整个ScrollView 需要在ScrollView设置属性 android:fillViewport="true"。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true"
        android:scrollbars="none"
        >

        <HorizontalScrollView
            android:id="@+id/scroll_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scrollbarAlwaysDrawHorizontalTrack="false"
            android:scrollbars="none">

            <LinearLayout
                android:id="@+id/MyTable"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_marginBottom="9dp"
                android:orientation="vertical"
                >
            </LinearLayout>

        </HorizontalScrollView>
    </ScrollView>
</LinearLayout>

　　3、接下来写表格显示的样式文件table.xml。该布局文件用来显示表格每一行的样式。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="match_parent">

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_1"
        android:layout_width="50dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_2"
        android:layout_alignTop="@+id/list_1_2"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_2"
        android:layout_width="180dp"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/list_1_1"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_3"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_2"
        android:layout_alignTop="@+id/list_1_2"
        android:layout_toRightOf="@+id/list_1_2"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_4"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_3"
        android:layout_alignTop="@+id/list_1_3"
        android:layout_toRightOf="@+id/list_1_3"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_5"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_4"
        android:layout_alignTop="@+id/list_1_4"
        android:layout_toRightOf="@+id/list_1_4"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_6"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_5"
        android:layout_alignTop="@+id/list_1_5"
        android:layout_toRightOf="@+id/list_1_5"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_7"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_6"
        android:layout_alignTop="@+id/list_1_6"
        android:layout_toRightOf="@+id/list_1_6"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />
</RelativeLayout>

　　4、最后把数据放到我们的table.xml文件中，并显示到我们的主布局文件中。

package lyf.com.mytableview;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;

/**
 * lyf on 2016/06/27
 * 自定义表格显示
 */

public class MainActivity extends Activity {

    private LinearLayout mainLinerLayout;
    private RelativeLayout relativeLayout;
    private String[] name={"序号","考号","姓名","出生年月","语文","数学","英语"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mainLinerLayout = (LinearLayout) this.findViewById(R.id.MyTable);
        initData();
    }

    //绑定数据
    private void initData() {
        //初始化标题
        relativeLayout = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.table, null);
        MyTableTextView title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_1);
        title.setText(name[0]);
        title.setTextColor(Color.BLUE);

        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_2);
        title.setText(name[1]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_3);
        title.setText(name[2]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_4);
        title.setText(name[3]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_5);
        title.setText(name[4]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_6);
        title.setText(name[5]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_7);
        title.setText(name[6]);
        title.setTextColor(Color.BLUE);
        mainLinerLayout.addView(relativeLayout);

        //初始化内容
        int number = 1;
        for (int i=0;i<10;i++) {
            relativeLayout = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.table, null);
            MyTableTextView txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_1);
            txt.setText(String.valueOf(number));

            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_2);
            txt.setText("320321**********35");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_3);
            txt.setText("张三");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_4);
            txt.setText("1992/04/21");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_5);
            txt.setText("150");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_6);
            txt.setText("200");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_7);
            txt.setText("120");
            mainLinerLayout.addView(relativeLayout);
            number++;
        }
    }
}
