Android自定义Dialog

这段时间在做一个项目，需要使用到自定义Dialog，先在网上找了一下资料，发现还是有很多没有讲清楚的，在此给出一个Demo，一来可以方便广大码农，二来也可以方便自己，以备不时之需。。。

一个app更新对话框

java代码：

package com.xiebao.util.dialog;

import android.app.Dialog;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;

import com.xiebao.R;
import com.xiebao.bean.VersionBean;

public class UpdateDialog extends Dialog {



    @Override
    public void setOnDismissListener(OnDismissListener listener) {
        // TODO Auto-generated method stub
        super.setOnDismissListener(listener);
        
    }

    private View updateButton;
    private View cancelButton;
    private TextView mVersionNoText;
    private TextView mUpdateMessageText;
    private VersionBean mVersion;
    private Context context;

    public UpdateDialog(Context context, VersionBean mVersion) {
        this(context, android.R.style.Theme_Translucent_NoTitleBar);
        this.mVersion = mVersion;
        this.context=context;
        showDialog();
    }

    private void showDialog() {
        if(!isShowing()){
            show();
        }
        
    }

    public UpdateDialog(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    public UpdateDialog(Context context, int theme) {
        super(context, theme);
        // TODO Auto-generated constructor stub
    }
   
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.update_version_view);
        initView();
        initListener();

    }

    private void initListener() {
        mVersionNoText.setText("版本 : " +mVersion.getNo());
        mUpdateMessageText.setText(mVersion.getDescription());
        updateButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                //要处理的业务
                link();
                canDialog();
                

            }
        });
        cancelButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                canDialog();

            }
        });

    }
    /**
     * 跳转浏览器
     */
    private void link() {
        // TODO Auto-generated method stub
        String url = mVersion.getUrl(); // web address
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.parse(url));
        context.startActivity(intent);
        }
    protected void canDialog() {
    if(isShowing()){
        dismiss();
    }
        
    }

    private void initView() {
        updateButton = findViewById(R.id.update_dialog_ok);
        cancelButton = findViewById(R.id.update_dialog_cancel);
        mVersionNoText = (TextView) findViewById(R.id.update_version);
        mUpdateMessageText = (TextView) findViewById(R.id.update_info);
    }

}
