Android实现类似execel的表格 能回显并能修改表格内容的方法

时间：2021-09-07 09:10:00|栏目：Android代码|点击： 次

如下所示：

自定义实现一个水平滚动控件HorizontalScrollView

package com.example.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.HorizontalScrollView;

/**
 * 自定义实现一个水平滚动控件HorizontalScrollView
 * @author Administrator
 *
 */
public class SyncHorizontalScrollView extends HorizontalScrollView {
  private View mView;

  public SyncHorizontalScrollView(Context context) {
   super(context);
  }

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

  public SyncHorizontalScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
   super(context, attrs, defStyleAttr);
  }

  protected void onScrollChanged(int l, int t, int oldl, int oldt) {
   super.onScrollChanged(l, t, oldl, oldt);
   if (mView != null) {
    mView.scrollTo(l, t);
   }
  }

  public void setScrollView(View view) {
   mView = view;
  }
}

自定义实现LinearLayout让其能跟着ScrollView滚动

 package com.example.view;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.LinearLayout;
import android.widget.ListView;

/**
 * 自定义实现LinearLayout让其能跟着ScrollView滚动
 * @author Administrator
 *
 */
public class NoscrollLinearLayout extends LinearLayout {


 public NoscrollLinearLayout(Context context) {
  super(context);
 }

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

 public NoscrollLinearLayout(Context context, AttributeSet attrs, int defStyleAttr) {
  super(context, attrs, defStyleAttr);
 }

 @Override
 protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
  int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
  super.onMeasure(widthMeasureSpec, expandSpec);
 }
}

自定义实现ListView让其能跟着ScrollView滚动

package com.example.view;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;

/**
 * 自定义实现ListView让其能跟着ScrollView滚动
 * @author Administrator
 *
 */
public class NoscrollListView extends ListView {

 public NoscrollListView(Context context) {
  super(context);
 }

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

 public NoscrollListView(Context context, AttributeSet attrs, int defStyleAttr) {
  super(context, attrs, defStyleAttr);
 }

 @Override
 protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
  int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
  super.onMeasure(widthMeasureSpec, expandSpec);
 }
}

显示数据的fragment

import android.app.Fragment;
import android.os.Bundle;
import android.text.TextUtils;

import android.view.LayoutInflater;

import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.EditText;

import com.example.auto.R;

/**
 * 显示数据的fragment
 * @author Administrator
 *
 */
public class ItemFragment extends Fragment {
 private EditText et_1,et_2,et_3,et_4,et_5;
 private ArrayList<EditText>list ;

  @Override 
  public void onCreate(Bundle savedInstanceState) 
  { 
   super.onCreate(savedInstanceState); 
   setHasOptionsMenu(true); 
  } 
  @Override 
 public View onCreateView(LayoutInflater inflater,
    ViewGroup container, Bundle savedInstanceState) {
  View view =inflater.inflate(R.layout.item_fragment,container, false);
  setView(view);
//  setListener();
  return view;
 }
 private void setListener() {

 }
 private void setView(View view) {
  list =new ArrayList<>();
  et_1=(EditText) view.findViewById(R.id.et_1);
  et_2=(EditText) view.findViewById(R.id.et_2);
  et_3=(EditText) view.findViewById(R.id.et_3);
  et_4=(EditText) view.findViewById(R.id.et_4);
  et_5=(EditText) view.findViewById(R.id.et_5);
  list.add( et_1);
  list.add( et_2);
  list.add( et_3);
  list.add( et_4);
  list.add( et_5);
 }
 private StringBuffer sb;
 public String getValue(){
  sb =new StringBuffer();
  for (int i = 0; i < list.size(); i++) {
   String string =list.get(i).getText().toString();
 /*  if (i==0) {
    if (string!=null) {
     sb.append(string);
     sb.append("$");
    }else {
     sb.append("-1");sb.append("$");
    }
   }else*/ if (i==list.size()-1) {
    if (!TextUtils.isEmpty(string)) {
     sb.append(string);
    }else {
     sb.append("-1");
    }
   }else {
    if (!TextUtils.isEmpty(string)) {
     sb.append(string);sb.append("$");
    }else {
     sb.append("-1");sb.append("$");
    }
   }
  }
  return sb.toString();
 }
 public void setXm(String string){
  if (!TextUtils.isEmpty(string)) {
   et_1.setText(string);
  }
 }
 public void setNl(String string){
  if (!TextUtils.isEmpty(string)) {
   et_2.setText(string);
  }
 }
 public void setTw(String string){
  if (!TextUtils.isEmpty(string)) {
   et_3.setText(string);
  }
 }
 public void setMb(String string){
  if (!TextUtils.isEmpty(string)) {
   et_4.setText(string);
  }
 }
 public void setHx(String string){
  if (!TextUtils.isEmpty(string)) {
   et_5.setText(string);
  }
 }

}
