自定义弹出框
自定义弹出框
第一步
在res的values中创建styles_dialog.xml文件
第二步
创建自定义xml布局文件
第三步
创建MyDialogUtil文件
package com.daodian.mydialogtestavtivity;
import android.app.AlertDialog;
import android.content.Context;
import android.text.TextUtils;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;
import android.widget.EditText;
import android.widget.TextView;
import androidx.databinding.DataBindingUtil;
import com.daodian.mydialogtestavtivity.databinding.LayoutMyDialogBinding;
public class MyDialogUtil {
private AlertDialog dialog;
private static MyDialogUtil myDialogUtil;
private MyDialogUtil(){
}
public static MyDialogUtil getDialogUtils(){
if(myDialogUtil == null){
myDialogUtil = new MyDialogUtil();
}
return myDialogUtil;
}
/**
* @param context
* @param title 标题
* @param content 内容
* @param hint 编辑框提示信息
* @param leftBtn 左边的文本按钮
* @param rightBtn 右边的文本按钮
*/
public void showDialog(final Context context, String title, String content, String hint, String leftBtn, String rightBtn){
View view = LayoutInflater.from(context).inflate(R.layout.layout_my_dialog, null);
TextView dialog_title = view.findViewById(R.id.dialog_title);
TextView dialog_content = view.findViewById(R.id.dialog_content);
final EditText dialog_edit = view.findViewById(R.id.dialog_edit);
TextView cancel = view.findViewById(R.id.cancel);
TextView confirm = view.findViewById(R.id.confirm);
if (TextUtils.isEmpty(title)){
dialog_title.setVisibility(View.GONE);
}else{
dialog_title.setText(title);
}
if (TextUtils.isEmpty(content)){
dialog_content.setVisibility(View.GONE);
}else{
dialog_content.setText(content);
}
if (TextUtils.isEmpty(hint)){
dialog_edit.setVisibility(View.GONE);
}else{
dialog_edit.setHint(hint);
}
cancel.setText(leftBtn);
confirm.setText(rightBtn);
cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
cancel();
}
});
confirm.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String data = dialog_edit.getText().toString();
if (TextUtils.isEmpty(data)){
ToastUtil.getToast().showToast(context, "输入框不能为空");
}else{
ToastUtil.getToast().showToast(context, data);
cancel();
}
}
});
initView(context, view, false, false);
}
/**
* @param context
* @param title 标题
* @param content 内容
* @param hint 编辑框提示信息
* @param leftBtn 左边的文本按钮
* @param rightBtn 右边的文本按钮
*/
public void showDialog2(final Context context, String title, String content, String hint, String leftBtn, String rightBtn){
LayoutMyDialogBinding binding = DataBindingUtil.inflate(LayoutInflater.from(context), R.layout.layout_my_dialog,null, false);
if (TextUtils.isEmpty(title)){
binding.dialogTitle.setVisibility(View.GONE);
}else{
binding.dialogTitle.setText(title);
}
if (TextUtils.isEmpty(content)){
binding.dialogContent.setVisibility(View.GONE);
}else{
binding.dialogContent.setText(content);
}
if (TextUtils.isEmpty(hint)){
binding.dialogEdit.setVisibility(View.GONE);
}else{
binding.dialogEdit.setHint(hint);
}
binding.cancel.setText(leftBtn);
binding.confirm.setText(rightBtn);
binding.cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
cancel();
}
});
binding.confirm.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String data = binding.dialogEdit.getText().toString();
if (TextUtils.isEmpty(data)){
ToastUtil.getToast().showToast(context, "输入框不能为空");
}else{
ToastUtil.getToast().showToast(context, data);
cancel();
}
}
});
initView(context, binding.getRoot(), false, false);
}
/**
*
* @param context
* @param view
* @param canceledOnTouchOutside 点击外面是否消失 true点击外面可以消失
* @param cancelable false的话 点击屏幕和返回按键都不会消失 默认是true
* @return
*/
private AlertDialog initView(Context context, View view, boolean canceledOnTouchOutside, boolean cancelable){
dialog = new AlertDialog.Builder(context, R.style.myDialog).create();
dialog.setCanceledOnTouchOutside(canceledOnTouchOutside);
dialog.setCancelable(cancelable);
view.setLayoutParams(new WindowManager.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
dialog.setView(view, 0, 0, 0, 0);
dialog.show();
return dialog;
}
public void cancel(){
if (dialog != null && dialog.isShowing()){
dialog.cancel();
}
if (myDialogUtil != null){
myDialogUtil = null;
}
}
}
showDialog2和showDialog的运行结果是一样的，showDialog2是使用DataBinding绑定id，代码更简洁
第四步
调用显示弹出框
package com.daodian.mydialogtestavtivity;
import androidx.appcompat.app.AppCompatActivity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import butterknife.ButterKnife;
import butterknife.OnClick;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
}
@OnClick(R.id.btn1)
public void btn1(){
MyDialogUtil.getDialogUtils().showDialog2(this, "", "内容", "", "确定", "");
}
@OnClick(R.id.btn2)
public void btn2(){
MyDialogUtil.getDialogUtils().showDialog2(this, "", "", "提示信息", "", "确定");
}
@OnClick(R.id.btn3)
public void btn3(){
MyDialogUtil.getDialogUtils().showDialog2(this, "标题", "内容", "提示信息", "取消", "确定");
}
}
