Android Dialog的封装

常规使用：

                Dialog dialog=new Dialog(this,R.style.DialogStyle);                View dilaogView = LayoutInflater.from(this).inflate(                        R.layout.dialog_diylayout, null);                dialog.setContentView(dilaogView);                dialog.show();

如果需要设置dialog的弹出位置，则需要用到Window，通过setGravity来控制dialog位置

        Dialog  dialog = new Dialog(context, R.style.DialogStyle);        Window win = dialog.getWindow();        win.getDecorView().setPadding(0, 0, 0, 0);        WindowManager.LayoutParams lp = win.getAttributes();        // 设置弹出框的宽高        lp.width = WindowManager.LayoutParams.WRAP_CONTENT;        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;        // 设置弹出框的位置        win.setGravity(Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL);        win.setAttributes(lp);        win.setContentView(R.layout.dialog_gravity);        dialog.show();

之后就是封装Dialog了

我们把dialog的初始化，findView和设置点击事件都封装在一个类里，在给出一些set方法和接口

import android.app.Dialog;import android.content.Context;import android.text.TextUtils;import android.view.LayoutInflater;import android.view.View;import android.widget.TextView;import com.diydialog.R;/** * Created by KID on 2018/1/18. */public class DiyDialog {    private Context context;    private Dialog dialog;    private TextView tv_dialog_content;    private TextView tv_cancle;    private TextView tv_ok;    private String content;    private String cancle;    private String ok ;    public DialogClickListener dialogClickListener;    public void setDialogClickListener(DialogClickListener dialogClickListener){        this.dialogClickListener=dialogClickListener;    }    public DiyDialog setContent(String content) {        this.content = content;        return this;    }    public DiyDialog setCancle(String cancle) {        this.cancle = cancle;        return this;    }    public DiyDialog setOk(String ok) {        this.ok = ok;        return this;    }    public DiyDialog(Context context){        this.context=context;    }    public DiyDialog builder(){        View view = LayoutInflater.from(context).inflate(                R.layout.dialog_diylayout, null);        tv_dialog_content= (TextView) view.findViewById(R.id.tv_dialog_content);        tv_cancle= (TextView) view.findViewById(R.id.tv_cancle);        tv_ok= (TextView) view.findViewById(R.id.tv_ok);        if(!TextUtils.isEmpty(content))tv_dialog_content.setText(content);        if(!TextUtils.isEmpty(cancle))tv_cancle.setText(cancle);        if(!TextUtils.isEmpty(ok))tv_ok.setText(ok);        tv_cancle.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                if(dialogClickListener!=null)dialogClickListener.cancle();            }        });        tv_ok.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                if(dialogClickListener!=null)dialogClickListener.ok();            }        });        dialog = new Dialog(context, R.style.DialogStyle);        dialog.setContentView(view);        return this;    }    public void show() {        if(dialog!=null)dialog.show();    }    public void cancle() {        if(dialog!=null)dialog.cancel();    }    public interface DialogClickListener{        void cancle();        void ok();    }}

使用这个封装dialog的代码

                final DiyDialog diyDialog =new DiyDialog(this);                diyDialog.setCancle("No").setOk("Yes").setContent("Are you kidding me?");                diyDialog.setDialogClickListener(new DiyDialog.DialogClickListener() {                    @Override                    public void cancle() {                        diyDialog.cancle();                    }                    @Override                    public void ok() {                        diyDialog.cancle();                        Toast.makeText(MainActivity.this, "ok哟呵呵呵呵", Toast.LENGTH_SHORT).show();                    }                });                diyDialog.builder().show();

当然你也可以写成一整条链式过去，个人风格问题，比较喜欢分开写。

如果需要弹出动画

win.setWindowAnimations(R.style.mystyle);

dialog_enter.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">    <translate        android:fromYDelta="100%p"        android:duration="300" />set>

dialog_exit.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">    <translate        android:toYDelta="100%p"        android:duration="300" />set>

上面new Dialog的时候传入的 R.style.DialogStyle只是一个样式，非必传。不过建议还是加上,在styles.xml中插入
