这篇文章主要为大家详细介绍了非常实用的侧滑删除控件SwipeLayout,类似于QQ侧滑点击删除效果,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

前言:项目中经常会用到类似于QQ侧滑点击删除的效果,网上的开源库也很多。个人感觉SwipeLayout最好用。下面介绍怎么使用。

一、首先导入需要的Jar包,有3个,AndroidSwipeLayout-v1.1.8.jar、AndroidViewAnimations-1.1.3.jar、nineoldandroids-2.4.0.jar。第一个jar包就是我们使用该控件的jar包,后面2个是侧滑出现删除menu的动画所需的jar包。下面就是怎么使用了。

主布局的xml文件如下,就是一个ListView:

<?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" >

  <ListView
    android:id="@+id/swipe_listview"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
  </ListView>

</LinearLayout>

listview中的每个Item的布局如下:

<?xml version="1.0" encoding="utf-8"?>
<com.daimajia.swipe.SwipeLayout xmlns:swipe="http://schemas.android.com/apk/res-auto"
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/swipe"
  android:layout_width="match_parent"
  android:layout_height="wrap_content" >

  <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="80dp"
    android:background="#FF5534"
    android:gravity="center"
    android:tag="Bottom3"
    android:weightSum="10" >

    <ImageView
      android:id="@+id/trash"
      android:layout_width="27dp"
      android:layout_height="30dp"
      android:layout_weight="1"
      android:src="@drawable/trash" />

    <TextView
      android:layout_width="0dp"
      android:layout_height="wrap_content"
      android:layout_weight="5"
      android:text="Delete Item?"
      android:textColor="#fff"
      android:textSize="17sp" />

    <Button
      android:id="@+id/delete"
      android:layout_width="0dp"
      android:layout_height="40dp"
      android:layout_weight="4"
      android:background="@drawable/white"
      android:text="Yes,Delete"
      android:textColor="#FF5534" />
  </LinearLayout>

  <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/item_selector"
    android:padding="10dp" >

    <TextView
      android:id="@+id/position"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" />

    <TextView
      android:id="@+id/text_data"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:tag="Hover"
      android:text="Just Do it . " />
  </LinearLayout>

上面的那个LinerLayout相当于bottomView,下面的那个相对应于SurfaceView。开始的时候SurfaceView显示在手机屏幕上,而bottomView则在屏幕外,随着手指的滑动渐渐显示在屏幕上。

Adapter.java如下:

package com.example.adapter;

import java.util.List;

import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.TextView;
import android.widget.Toast;

import com.daimajia.androidanimations.library.Techniques;
import com.daimajia.androidanimations.library.YoYo;
import com.daimajia.swipe.SimpleSwipeListener;
import com.daimajia.swipe.SwipeLayout;
import com.daimajia.swipe.adapters.BaseSwipeAdapter;
import com.example.firstactivity.R;

public class ListViewAdapter extends BaseSwipeAdapter {

  private Context mContext;
  private List<String> mDatas;
  //private TextView mDelete;
  //private SwipeLayout swipeLayout;
  private int pos ;

  public ListViewAdapter(Context context, List<String> mDatas) {
    this.mContext = context;
    this.mDatas = mDatas;
  }

  @Override
  public int getCount() {
    // TODO Auto-generated method stub
    return mDatas.size();
  }

  @Override
  public Object getItem(int position) {
    // TODO Auto-generated method stub
    return mDatas.get(position);
  }

  @Override
  public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
  }

  @Override
  public void fillValues(int position, View convertView) {
    // TODO Auto-generated method stub
    Log.e("fillValues", "position = "+position);
    TextView tv = (TextView) convertView.findViewById(R.id.position);
    //tv.setText((position + 1) + ".");
    tv.setText(mDatas.get(position)+"....");

    final SwipeLayout sl = (SwipeLayout) convertView.findViewById(getSwipeLayoutResourceId(position));
    final TextView delete = (TextView) convertView.findViewById(R.id.delete);
    delete.setTag(position);
    delete.setOnClickListener(new OnClickListener() {

      @Override
      public void onClick(View v) {
        // TODO Auto-generated method stub
        int pos = (Integer) delete.getTag();
        String obj = mDatas.get(pos);

        Log.e("onClick", "........pos ...."+pos+" obj = "+obj);
        mDatas.remove(obj);
        notifyDataSetChanged();
        sl.close();
      }
    });

  }

  @Override
  public View generateView(int position, ViewGroup arg1) {
    // TODO Auto-generated method stub
    Log.e("generateView", "position = "+position);
    View v = LayoutInflater.from(mContext).inflate(R.layout.swipe_lv_item,null);
    pos = position;
    final SwipeLayout swipeLayout = (SwipeLayout) v.findViewById(R.id.swipe);

    swipeLayout.addSwipeListener(new SimpleSwipeListener() {
      @Override
      public void onOpen(SwipeLayout layout) {//当隐藏的删除menu被打开的时候的回调函数
        // TODO Auto-generated method stub
        YoYo.with(Techniques.Tada).duration(500).delay(100).playOn(layout.findViewById(R.id.trash));

      }
    });

    swipeLayout.setOnDoubleClickListener(new SwipeLayout.DoubleClickListener() {
          @Override
          public void onDoubleClick(SwipeLayout layout,
              boolean surface) {
            Toast.makeText(mContext, "DoubleClick",Toast.LENGTH_SHORT).show();

          }
        });
//   v.findViewById(R.id.delete).setOnClickListener(
//       new View.OnClickListener() {
//         @Override
//         public void onClick(View view) {
//           Toast.makeText(mContext, "click delete position = "+pos,Toast.LENGTH_SHORT).show();
//           swipeLayout.close();
//         }
//       });

    return v;
  }

  @Override
  public int getSwipeLayoutResourceId(int position) {
    // TODO Auto-generated method stub
    return R.id.swipe;
  }

}

注意, generateView只是加布局,最好不要在里面设置点击事件。点击事件设置fillValues这个方法中。

Activity.java如下:

package com.example.firstactivity;

import java.util.ArrayList;
import java.util.List;

import com.example.adapter.ListViewAdapter;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;

import com.daimajia.swipe.util.Attributes;

public class SwipeListViewActivity extends Activity{

  private ListView mListView;
  private ListViewAdapter mAdapter;
  private List<String> mDatas;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.swipe_layout_main);

    getData();

    mListView = (ListView) findViewById(R.id.swipe_listview);
    mAdapter = new ListViewAdapter(this, mDatas);
    mAdapter.setMode(Attributes.Mode.Single);
    mListView.setAdapter(mAdapter);
  }

  public void getData(){
    mDatas = new ArrayList<String>();
    //for(int i =0; i<10; i++){
      mDatas.add("A");
      mDatas.add("B");
      mDatas.add("C");
      mDatas.add("D");
      mDatas.add("E");
      mDatas.add("F");
      mDatas.add("G");
      mDatas.add("H");
      mDatas.add("I");
      mDatas.add("J");


    //}
  }
}
