在实际的开发当中，我们APP项目中的各种提示框都是统一的。为了避免重复的代码和样式的不同，所以我们需要定义一个统一样式的提示框！代码示例如下：
package com.wly.home.widget;import com.wanbu.dascom.R;import android.app.Dialog;import android.content.Context;import android.text.Editable;import android.text.TextWatcher;import android.view.View;import android.widget.EditText;import android.widget.TextView;/** * 统一样式的Dialog * @author wangly * */public class CommonDialog extends Dialog implements android.view.View.OnClickListener {    private TextView tv_title;    private TextView tv_info;    private EditText et_inputInfo;    private TextView tv_number;    private TextView tv_cancle;    private TextView tv_ok;    private CallBackListener listener;    public void setListener(CallBackListener listener) {        this.listener = listener;    }    public CommonDialog(Context context) {        super(context,R.style.commonDialog_style);        intView();    }    private void intView() {        setContentView(R.layout.common_layout_dialog);        tv_title = (TextView) findViewById(R.id.tv_title);        tv_info = (TextView) findViewById(R.id.tv_info);        et_inputInfo = (EditText) findViewById(R.id.et_inputInfo);        et_inputInfo.addTextChangedListener(watcher);        tv_number = (TextView) findViewById(R.id.tv_number);        tv_cancle = (TextView) findViewById(R.id.tv_cancle);        tv_ok = (TextView) findViewById(R.id.tv_ok);        tv_cancle.setOnClickListener(this);        tv_ok.setOnClickListener(this);    }    /**     * 设置标题     * @param text     * @param flag 显示/隐藏     */    public void setTiltle(String text,int flag){        tv_title.setText(text);        tv_title.setVisibility(flag);    }    /**     * 设置Dialog描述信息     * @param text     * @param flag 显示/隐藏     */    public void setInfo(String text,int flag){        tv_info.setText(text);        tv_info.setVisibility(flag);    }    /**     * 设置 "取消" 按钮文字     * @param text     */    public void setCancleText(String text){        tv_cancle.setText(text);    }    /**     * 设置 "确定" 按钮文字     * @param text     */    public void setConfirmText(String text){        tv_ok.setText(text);    }    @Override    public void onClick(View v) {        switch (v.getId()) {        case R.id.tv_cancle:            if (listener!=null) {                listener.cancleListener();            }            break;        case R.id.tv_ok:            if (listener!=null) {                listener.confirmListener(et_inputInfo.getText().toString().trim());            }            break;        default:            break;        }    }    /**     * EditText 字符控制     */    int num = 100;//限制的最大字数     TextWatcher watcher =new  TextWatcher(){        private CharSequence temp;        private int selectionStart;        private int selectionEnd;         @Override        public void beforeTextChanged(CharSequence s, int start, int count,                int after) {        }        @Override        public void onTextChanged(CharSequence s, int start, int before,                int count) {            temp = s;         }        @Override        public void afterTextChanged(Editable s) {            int number = num - s.length();            tv_number.setText(s.length()+"/100");            selectionStart = et_inputInfo.getSelectionStart();            selectionEnd = et_inputInfo.getSelectionEnd();            if (temp.length() > num) {                s.delete(selectionStart - 1, selectionEnd);                int tempSelection = selectionEnd;                et_inputInfo.setText(s);                et_inputInfo.setSelection(tempSelection);//设置光标在最后            }        }    };    public interface CallBackListener{        /**         * 取消         */        void cancleListener();        /**         * 确定         *  获取EditText 输入的内容         */        void confirmListener(String text);    }}<style name="commonDialog_style" parent="@android:Theme.Dialog">        <item name="android:windowNoTitle">true</item>        <item name="android:windowIsFloating">true</item>        <item name="android:windowContentOverlay">@null</item>        <item name="android:windowBackground">@drawable/update_dialog_shape</item>    </style>
