(Android review)dialog的使用
一、基本知识点
常见的dialog
基本代码:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
AlertDialog dialog = builder.create();
dialog.show();
1)常见对话框
builder.setMessage("浏览传智播客的网站");
builder.setPositiveButton
2)选择对话框
builder.setItems(items, new DialogInterface.OnClickListener()
items是一个选项内容的数组
3)单选对话框
builder.setSingleChoiceItems(items, 0, new DialogInterface.OnClickListener()
第二个参数:默认选中的按钮
4)多选对话框
builder.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener()
5)自定义对话框
LayoutInflater mInflater = LayoutInflater.from(this);
View view = mInflater.inflate(R.layout.custom_dialog, null);
builder.setView(view);
二、示例代码
1、MainActivity
package com.example.dialogtest; import android.os.Bundle; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.content.DialogInterface.OnClickListener; import android.content.DialogInterface.OnMultiChoiceClickListener; import android.view.LayoutInflater; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.Toast; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public void commondialog(View view){ AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setCancelable(false); builder.setTitle("女神"); builder.setMessage("章泽天是你的女神吗?"); builder.setPositiveButton("确定", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }); builder.setNeutralButton("隐藏", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub } }); builder.setNegativeButton("取消", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }); AlertDialog dialog = builder.create(); dialog.show(); } public void selectdialog(View view){ AlertDialog.Builder builder = new AlertDialog.Builder(this); final String items[] = new String[]{ "章泽天", "章泽天1", "章泽天2", "章泽天3" }; builder.setTitle("选择女神"); builder.setItems(items, new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(getApplicationContext(), items[which], 0).show(); } }); AlertDialog dialog = builder.create(); dialog.show(); } public void singleselectdialog(View view){ AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("选择女神"); final String items[] = new String[]{ "章泽天", "章泽天1", "章泽天2", "章泽天3" }; builder.setSingleChoiceItems(items, 0, new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(getApplicationContext(), items[which], 0).show(); } }); builder.setPositiveButton("确定", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }); AlertDialog dialog = builder.create(); dialog.show(); } public void multiselectdialog(View view){ AlertDialog.Builder builder = new AlertDialog.Builder(this); final String items[] = new String[]{ "章泽天", "章泽天1", "章泽天2", "章泽天3", }; final boolean checkedItems[] = new boolean[]{ true,false,false,false }; builder.setTitle("选择女神"); builder.setMultiChoiceItems(items, checkedItems, new OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { Toast.makeText(getApplicationContext(), items[which], 0).show(); } }); builder.setPositiveButton("确定", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }); AlertDialog dialog = builder.create(); dialog.show(); } public void customdialog(View view){ LayoutInflater inflater = LayoutInflater.from(this); View mView = inflater.inflate(R.layout.custom_dialog, null); AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("请输入用户信息"); builder.setView(mView); final AlertDialog dialog = builder.create(); dialog.show(); Button okBtn = (Button) mView.findViewById(R.id.bt_ok); okBtn.setOnClickListener(new View.OnClickListener() {//注意,这个demo用到了两个OnClickListener.所以这里需要加上View @Override public void onClick(View v) { dialog.dismiss(); } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } }
