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
package com.example.fragment; import java.util.ArrayList; import android.app.Fragment; import android.os.Bundle; import android.text.TextUtils; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.View.MeasureSpec; 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 ArrayListlist ; @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); } } }
