Dialog的自定义使用和普通使用

1.自定义界面加载弹框的代码模版(模拟输入密码)

//第一次进入设置密码界面private void showSetPasswordDialog() {    //创建提示框    final AlertDialog.Builder builder = new AlertDialog.Builder(HomeActivity.this);    //加载布局    View view = View.inflate(getApplicationContext(), R.layout.home_setuopassword, null);    //设置布局    builder.setView(view);    //找到控件    mFirstpassword = (EditText) view.findViewById(R.id.home_setpassword_frist);    mTwopassword = (EditText) view.findViewById(R.id.home_setpassword_two);    mCanle = (Button) view.findViewById(R.id.home_setpassword_canle);    mOk = (Button) view.findViewById(R.id.home_setpassword_ok);    //设置点击事件    mCanle.setOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View view) {            //点击取消            mDialog.dismiss();        }    });    //点击确定    mOk.setOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View view) {            //获取到输入的密码            String password = mFirstpassword.getText().toString().trim();            String passwords = mTwopassword.getText().toString().trim();            //判断是否为空            if (TextUtils.isEmpty(password) || TextUtils.isEmpty(passwords)){                Toast.makeText(HomeActivity.this, "密码不能为空", Toast.LENGTH_SHORT).show();            }else {                //判断是否相等               if (!password.equals(passwords)){                   Toast.makeText(HomeActivity.this, "输入的密码不同",                        Toast.LENGTH_SHORT).show();                }else {                   //保存密码                   SpUitls.setString(getApplicationContext(),Constaints.PASSWORLD,passwords);                   Toast.makeText(HomeActivity.this, "设置成功", Toast.LENGTH_SHORT).show();                   //跳转页面                    Intent intent = new Intent(HomeActivity.this,Setup1Activity.class);                   startActivity(intent);               }            }        }    });    mDialog = builder.show();}

2.XML代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"              android:layout_width="match_parent"              android:layout_height="match_parent"              android:orientation="vertical">    <TextView        style="@style/tille"        android:text="设置密码"/>    <EditText        android:id="@+id/home_setpassword_frist"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:layout_marginTop="5dp"        android:hint="请输入密码"        android:inputType="textPassword"        android:textColor="#000"/>    <EditText        android:id="@+id/home_setpassword_two"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:hint="请再次输入密码"        android:inputType="textPassword"        android:textColor="#000"/>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal">        <Button            android:id="@+id/home_setpassword_canle"            android:background="@drawable/buttn_digo"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:text="取消"            android:layout_marginLeft="5dp"/>        <Button            android:id="@+id/home_setpassword_ok"            android:layout_marginLeft="5dp"            android:background="@drawable/buttn_digo"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:text="确定"            android:layout_marginRight="5dp"/>    </LinearLayout></LinearLayout>

2.普通的弹框

代码实例

 //弹出对话框    AlertDialog.Builder builder = new AlertDialog.Builder(BlackNumberActivity.this);    builder.setTitle("警告");    builder.setMessage("是否删除此联系人");    builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {        @Override        public void onClick(DialogInterface dialogInterface, int i) {             ..........                mDialog.dismiss();            }else {                Toast.makeText(BlackNumberActivity.this, "删除失败", Toast.LENGTH_SHORT).show();                mDialog.dismiss();            }        }    });    builder.setNeutralButton("取消",null);    mDialog = builder.show();}
