原来处理方法是重写ListView
import android.content.Context; import android.util.AttributeSet; import android.view.MotionEvent; import android.widget.ListView; public class MyListView extends ListView { public MyListView(Context context) { super(context); // TODO Auto-generated constructor stub } public MyListView(Context context, AttributeSet attrs) { super(context, attrs); } public MyListView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, expandSpec); } @Override public boolean dispatchTouchEvent(MotionEvent ev) { if(ev.getAction() == MotionEvent.ACTION_MOVE){ return true; } return super.dispatchTouchEvent(ev); } }
试了这种方法还是显示不全 总是少二项内容
又使用了
public static void setListViewHeightBasedOnChildren(ListView listView) { // 获取ListView对应的Adapter ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) { return; } int totalHeight = 0; for (int i = 0, len = listAdapter.getCount(); i < len; i++) { // listAdapter.getCount()返回数据项的数目 View listItem = listAdapter.getView(i, null, listView); listItem.measure(0, 0); // 计算子项View 的宽高 totalHeight += listItem.getMeasuredHeight(); // 统计所有子项的总高度 } ViewGroup.LayoutParams params = listView.getLayoutParams(); params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)); // listView.getDividerHeight()获取子项间分隔符占用的高度 // params.height最后得到整个ListView完整显示需要的高度 listView.setLayoutParams(params); }
还是一样效果 少二项内容
最后在网上找到有人重写LinearLayout显示列表
import android.content.Context; import android.util.AttributeSet; import android.util.Log; import android.util.TypedValue; import android.view.View; import android.widget.AdapterView.OnItemClickListener; import android.widget.BaseAdapter; import android.widget.LinearLayout; /*** * * @author FreePC * */ public class LinearLayoutForListView extends LinearLayout { private BaseAdapter adapter; private OnItemClickListener onItemClickListener; /** * 通过 Java代码 实例化 * @param context */ public LinearLayoutForListView(Context context) { super(context); //设置LinearLayoutForListView为垂直布局，否者默认为水平布局，容易疏忽导致子项显示不全 LinearLayoutForListView.this.setOrientation(LinearLayout.VERTICAL); } /** * 此构造函数可以允许我们通过 XML的方式注册 控件 * @param context * @param attrs */ public LinearLayoutForListView(Context context, AttributeSet attrs) { super(context, attrs); LinearLayoutForListView.this.setOrientation(LinearLayout.VERTICAL); } /** * 设置适配器 * * @param adpater */ public void setAdapter(BaseAdapter adpater) { this.adapter = adpater; bindLinearLayout(); } /** * 获取适配器Adapter * * @return adapter */ public BaseAdapter getAdpater() { return adapter; } /** * 绑定布局:将每个子项的视图view添加进此线性布局LinearLayout中 */ public void bindLinearLayout() { int count = adapter.getCount(); for (int i = 0; i < count; i++) { View v = adapter.getView(i, null, null); if (i != count - 1) { //添加每项item之间的分割线 v = addLine(v); } addView(v, i); } setItemClickListener(); Log.v("countTAG", "" + count); } /** * 添加每项item之间的分割线 * * @param view * @return */ public View addLine(View view) { //分割线view View lineView = new View(view.getContext()); // 将数据从dip(即dp)转换到px，第一参数为数据原单位（此为DIP），第二参数为要转换的数据值 float fPx = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, (float) 0.5, view.getResources().getDisplayMetrics()); int iPx = Math.round(fPx); LayoutParams layoutParams = new LayoutParams( LinearLayout.LayoutParams.MATCH_PARENT, iPx); lineView.setLayoutParams(layoutParams); lineView.setBackgroundColor(view.getSolidColor()); LinearLayout ly = new LinearLayout(view.getContext()); ly.setOrientation(LinearLayout.VERTICAL); ly.addView(view); ly.addView(lineView); return ly; } /** * 设置点击子项事件监听对象 * @param onItemClickListener */ public void setOnItemClickListener(OnItemClickListener onItemClickListener) { this.onItemClickListener = onItemClickListener; setItemClickListener(); } /** * 获取点击子项事件监听对象 * @return */ public OnItemClickListener getOnItemClickListener() { return onItemClickListen
这种方法完全可以搞定，在原来开发当中 上面二个方法都可以搞定不知道这次为什么不行
我怀疑是布局问题
<ScrollView android:id="@id/myscrollview" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/v_common_line_color" android:orientation="vertical" android:scrollbars="none" > <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="8.0dip" android:orientation="vertical" > <FrameLayout android:id="@id/frame_layout" android:layout_width="match_parent" android:layout_height="wrap_content" > <ImageView android:layout_width="match_parent" android:layout_height="200.0dip" android:background="@drawable/home_cover2" android:scaleType="centerCrop" /> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom|left" android:layout_marginBottom="8.0dip" android:layout_marginLeft="16.0dip" > <TextView android:id="@id/txt_city" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="@color/white" android:textSize="@dimen/font18" /> <TextView android:id="@id/txt_weather" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/txt_city" android:layout_gravity="bottom|left" android:textColor="@color/white" android:textSize="@dimen/font18" /> </RelativeLayout> </FrameLayout> <LinearLayout android:id="@id/linear_title" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@id/frame_layout" android:layout_marginTop="8.0dp" android:background="@drawable/layout_background_corners" android:orientation="vertical" android:padding="8.0dip" > <TextView android:id="@id/txtTitle" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center_vertical" android:textColor="@color/black2" android:textSize="@dimen/font16" /> </LinearLayout> <ListView android:id="@id/liv_trip" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@id/linear_title" android:layout_marginBottom="8.0dip" android:layout_marginTop="8.0dip" android:divider="@color/cccccc" android:dividerHeight="0px" android:fadingEdge="none" /> </RelativeLayout> </ScrollView>
item布局是
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:background="@color/v_common_line_color"> </LinearLayout>
android scrollview listview显示不全
