Android带参数回传的自定义dialog

Android带参数回传的自定义dialog

1.首先，建立一个属于dialog的style样式：

    <style name="MessageListDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowIsTranslucent">false</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <!-- 无标题 -->
        <item name="android:windowNoTitle">true</item>
        <!-- 背景透明 -->
        <item name="android:backgroundDimEnabled">true</item>
        <item name="android:textColor">@color/black</item>
    </style>

样式大家可以看着酌量增减。
2.以下为自定义dialog的精华，大家品味以下。0.0

import android.app.Dialog;
import android.content.Context;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import com.fujitsu.R;
import com.fujitsu.adapter.Dialog_ChooseUserAdapter;

import java.util.ArrayList;
import java.util.HashMap;

/**

public class Dialog_ChooseUser extends Dialog implements AdapterView.OnItemClickListener{
    private Context context;
    private ListView listview;
    private ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
    private OnTextInputFinishedListener mListener; //接口

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        mListener.editInputFinished(list.get(position));
        dismiss();
    }

    public interface OnTextInputFinishedListener{
        void editInputFinished(HashMap<String, String> user);
    }

    public Dialog_ChooseUser(Context context, int theme, OnTextInputFinishedListener mListener) {
        super(context, theme);
        this.context = context;
        this.mListener = mListener;
        this.setCancelable(true);
        initView();
        initData();
    }

    private void initData() {
        HashMap<String, String> map = new HashMap<>();
        map.put("name","kate");
        map.put("password","1");
        HashMap<String, String> map1 = new HashMap<>();
        map1.put("name","john");
        map1.put("password","1");
        HashMap<String, String> map2 = new HashMap<>();
        map2.put("name","ming");
        map2.put("password","1");
        HashMap<String, String> map3 = new HashMap<>();
        map3.put("name","hirorin");
        map3.put("password","1");
        list.add(map);
        list.add(map1);
        list.add(map2);
        list.add(map3);
        Dialog_ChooseUserAdapter adapter = new Dialog_ChooseUserAdapter(context, list);
        listview.setAdapter(adapter);
        listview.setOnItemClickListener(this);
    }

    private void initView() {
        setContentView(R.layout.dialog_chooseuser);
        listview = (ListView) findViewById(R.id.dialog_chooseuser_listview);
    }

}

里面的Dialog_ChooseUserAdapter相信不用给大家介绍了吧？不知道的可以另行搜索BaseAdapter的使用！欧耶！
其中的精华为：

private OnTextInputFinishedListener mListener; //接口

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    mListener.editInputFinished(list.get(position));
    dismiss();   //当点击以后关闭弹出框
}

public interface OnTextInputFinishedListener{
    void editInputFinished(HashMap<String, String> user);
}

3.再献上dialog中布局的代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:layout_width="400dp"
        android:layout_height="300dp"
        android:orientation="vertical"
        android:background="@drawable/shap_dialog_white"
        android:gravity="center">
        <TextView
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:text="选择用户"
            android:textSize="25sp"
            android:gravity="center"
            android:textColor="@color/black"/>
        <ListView
            android:id="@+id/dialog_chooseuser_listview"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:listSelector="#00000000">

        </ListView>
    </LinearLayout>
</LinearLayout>

4.当要调用的时候，直接来这一句：

                Dialog_ChooseUser dialog = new Dialog_ChooseUser(LoginActivity.this,
                        R.style.MessageListDialog, new Dialog_ChooseUser.OnTextInputFinishedListener() {

                    @Override
                    public void editInputFinished(HashMap<String, String> user) {
                        etLoginName.setText(user.get("name"));
                        etPassword.setText(user.get("password"));
                    }

                });// 创建Dialog并设置样式主题
                dialog.show();
                dialog.getWindow().setGravity(Gravity.CENTER);

注意：顺序是这样的！不然容易出来一个顺序错乱异常！

       dialog.show();
       dialog.getWindow().setGravity(Gravity.CENTER);

其中

R.style.MessageListDialog

就是你前面定义的style！

结束，谢谢大家观看，打赏个或者点个赞呗亲！
