Android自定义弹框样式

2023-07-18 03:38:03 72

弹框样式的自定义是通过改变v7包下的AlertDialog的Window对象的view及控制Window的宽高实现的。所有源码如下，其中自定义View的宽度设置为手机屏幕宽度的82%。

importandroid.app.Dialog;
importandroid.content.Context;
importandroid.support.v7.app.AlertDialog;
importandroid.text.TextUtils;
importandroid.view.LayoutInflater;
importandroid.view.View;
importandroid.view.Window;
importandroid.view.WindowManager;
importandroid.widget.LinearLayout;
importandroid.widget.TextView;

importcom.environment.protection.util.CommonUtil;

使用方式如下：链式调用，可查看源码自己选择使用。

CustomDialog.Builderbuilder=newCustomDialog.Builder(mContext);
builder.setTitle("自定义弹框")//默认为“提示”
.setMessage("自定义内容")
.setNegativeText("自定义取消文字")//默认为“取消”
.setPositiveText("自定义确认文字")//默认为“确认”
.setOnPositiveButtonClickListener(newCustomDialog.OnPositiveButtonClickListener(){
@Override
publicvoidonPositiveButtonClick(Dialogdialog){
ToastUtil.makeText(mContext,"自定义确认按钮监听逻辑处理");
}
})
.setOnNegativeButtonClickListener(newCustomDialog.OnNegativeButtonClickListener(){
@Override
publicvoidonNegativeButtonClick(Dialogdialog){
ToastUtil.makeText(mContext,"自定义取消按钮监听逻辑处理");
}
})
.setCancelable(false)//默认true
.build();

效果图如下，使用者可按照实际需要自定义xml文件进行更改：
