自定义Dialog和PopupWindow的具体实现代码

自定义Dialog类

     package com.jibaowang.chat.dialog;
    import android.app.Dialog;
    import android.content.Context;
    import android.view.Gravity;
    import android.view.View;
    import android.view.Window;
    import android.view.WindowManager;
    import android.widget.EditText;

    import com.jibaowang.chat.R;
    import com.jibaowang.chat.utils.DensityUtil;


    public class DialogJob implements View.OnClickListener {

    private Dialog mDialog;
    private EditText et_wirte;

    public DialogJob(Context context, IOnSexChanger onSexChanger){
        mIOnSexChanger = onSexChanger;
        initView(context);
    }

    public void initView(Context context){
        if(null ==context){
            return;
        }
        mDialog = new Dialog(context, R.style.dialog);
        mDialog.setCanceledOnTouchOutside(true);//设置点击弹窗外消失
        mDialog.setContentView(R.layout.dialog_job);
        mDialog.findViewById(R.id.iv_btn_cancle).setOnClickListener(this);
        mDialog.findViewById(R.id.iv_btn_submit).setOnClickListener(this);
        et_wirte=(EditText)mDialog.findViewById(R.id.et_wirte);

        Window win = mDialog.getWindow();   //给窗体设置大小
        win.getDecorView().setPadding(0, 0, 0, 0);
        WindowManager.LayoutParams lp = win.getAttributes();
        lp.width = WindowManager.LayoutParams.MATCH_PARENT;
        lp.height = DensityUtil.dp2px(context,160);
        win.setGravity(Gravity.CENTER);
        win.setAttributes(lp);
    }

    public void show(){
        if(null != mDialog){
            mDialog.show();
        }
    }

    public void dismiss(){
        if(null != mDialog && mDialog.isShowing()){
            mDialog.dismiss();
        }
    }

    @Override
    public void onClick(View v) {
        if(v.getId()==R.id.iv_btn_cancle){
            dismiss();
        }else if(v.getId()==R.id.iv_btn_submit){
            String strname = et_wirte.getText().toString();
            mIOnSexChanger.onJobChangerLitener(strname);
            dismiss();
        }
        dismiss();
    }

    private IOnSexChanger mIOnSexChanger;
    public interface IOnSexChanger{
        void onJobChangerLitener(String strname);
    }
    }

HeadPhotoPop类
