Android Dialog的封装

释放双眼,带上耳机,听听看~!

 

效果
这里写图片描述
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);

    <style name="mystyle" parent="android:Animation">
<item name="@android:windowEnterAnimation">@anim/dialog_enter</item>  //进入时的动画
<item name="@android:windowExitAnimation">@anim/dialog_exit</item>    //退出时的动画
</style>

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

    <!-- Dialog的样式 -->
<style name="DialogStyle" parent="@android:style/Theme.Dialog">
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowFrame">@null</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsTranslucent">true</item>
</style>
