DialogFragment的使用及利用自定义interface点击事件并解决旋转屏幕点击事件失效问题

前阵子一直比较忙，所以没怎么写。其实感觉项目中实用好东东还是挺多的，今天就来分享一个DialogFragment的简单使用和利用自定义接口来实现点击事件。
关于DialogFragment和dialog的具体区别，感兴趣的可以自己去了解学习。
因为之前项目是只能竖屏，所以当时没有考虑到横竖屏切换问题，等自己写demo的时候才发现，刚好在这里一并解决此问题。老规矩，先看效果图：

对就是这个样子。下来看看具体实现
1.ShareScoreDialog

package com.dialogfragmentdemo;

import android.app.Dialog;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.view.View;
import android.view.Window;
import android.widget.ImageView;
import android.widget.TextView;

/**

 */

public class ShareScoreDialog extends DialogFragment implements View.OnClickListener {

    TextView wx, wxq, qq;
    ImageView close;

//    private MyCheckDialogListener myCheckDialogListener;

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Dialog dialog = null;

            dialog = new Dialog(getActivity(),0);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);//代码中取消标题栏
            dialog.setContentView(R.layout.dialog_new_share_layout);
        dialog.getWindow().setBackgroundDrawable(newColorDrawable(android.graphics.Color.TRANSPARENT));
            wx = dialog.findViewById(R.id.share_weichat_dialog); //微信
            wxq = dialog.findViewById(R.id.share_weichat_friendq_dialog);//朋友圈
            qq = dialog.findViewById(R.id.share_qq_dialog);//qq
            close =dialog.findViewById(R.id.close);//右上角的叉
            wx.setOnClickListener(this);
            wxq.setOnClickListener(this);
            qq.setOnClickListener(this);
            close.setOnClickListener(this);
        return dialog;
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.close:
                dismiss();
                break;
            case R.id.share_weichat_dialog:
                dismiss();
                if(shareScoreDialogListener!=null)
                shareScoreDialogListener.share(1);
                break;

            case R.id.share_weichat_friendq_dialog:
                dismiss();
                if(shareScoreDialogListener!=null)
                    shareScoreDialogListener.share(2);
                break;

            case R.id.share_qq_dialog:
                dismiss();
                if(shareScoreDialogListener!=null)
                    shareScoreDialogListener.share(3);
                break;

            default:
                break;
        }
    }

    private ShareScoreDialogListener shareScoreDialogListener;
    public void setOnMyCheckDialogListener(ShareScoreDialogListener shareScoreDialogListener) {
        this.shareScoreDialogListener = shareScoreDialogListener;
    }

    public interface ShareScoreDialogListener {
        /**1微信 2朋友圈 3qq*/
        public void share(int type);
    }

}

代码比较简单，主要是这种写法和思路个人感觉比较好。可定制度极高。

然后就是怎么来调用了
2.MainActivity

package com.dialogfragmentdemo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements ShareScoreDialog.ShareScoreDialogListener {

    private Button button;

    private ShareScoreDialog shareScoreDialog;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (savedInstanceState!=null){
            shareScoreDialog = (ShareScoreDialog) getSupportFragmentManager().findFragmentByTag("shareScoreDialog");
        }
        if (shareScoreDialog!=null){
            shareScoreDialog.setOnMyCheckDialogListener(this);
        }
        setContentView(R.layout.activity_main);
        button = (Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showShareScoreDialog();
            }
        });
    }

    private void showShareScoreDialog() {
        if (shareScoreDialog == null){
            shareScoreDialog = new ShareScoreDialog();
            shareScoreDialog.setOnMyCheckDialogListener(this);
            shareScoreDialog.show(getSupportFragmentManager(), "shareScoreDialog");
        }else {
            shareScoreDialog.setOnMyCheckDialogListener(this);
            shareScoreDialog.show(getSupportFragmentManager(), "shareScoreDialog");
        }

    }

    @Override
    public void share(int type) {
        /**1微信 2朋友圈 3qq*/
        switch (type) {
            case 1:
                Toast.makeText(this,"微信",Toast.LENGTH_SHORT).show();
                break;
            case 2:
                Toast.makeText(this,"朋友圈",Toast.LENGTH_SHORT).show();
                break;
            case 3:
                Toast.makeText(this,"QQ",Toast.LENGTH_SHORT).show();
                break;
        }

    }




}

其中这段是用来解决如果dialog处于show时横竖屏切换后点击事前不起作用的

if (savedInstanceState!=null){
            shareScoreDialog = (ShareScoreDialog) getSupportFragmentManager().findFragmentByTag("shareScoreDialog");
        }
        if (shareScoreDialog!=null){
            shareScoreDialog.setOnMyCheckDialogListener(this);
        }

下来是xml，当时右上角那个xx费了点劲，直接也把这段代码贴上
3. dialog_new_share_layout
