自定义Dialog

一、效果

二、步骤

需要使用Dialog的setView方法，因此

1、编写布局文件

2、编写代码

三、各步骤具体代码

dialog_set_password.xml

<?xml version="1.0" encoding="utf-8"?>
<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/DialogTitle"
        android:text="@string/setPasswordTitle" />

    <EditText
        android:id="@+id/et_password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="请输入密码"
        android:inputType="textPassword" />

    <EditText
        android:id="@+id/et_password_confirm"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="请再次输入密码"
        android:inputType="textPassword" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <Button
            android:id="@+id/btn_ok"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="确定" />

        <Button
            android:id="@+id/btn_cancle"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="取消" />
    </LinearLayout>

</LinearLayout>

java代码：

/**
	 * 设置密码的弹窗
	 */
	private void showPasswordSetDialog(){
		
		AlertDialog.Builder builder=new AlertDialog.Builder(this);
		final AlertDialog dialog=builder.create();
		View view=View.inflate(this, R.layout.dialog_set_password, null);
		//dialog.setView(view);
		dialog.setView(view, 0, 0, 0, 0);//设置边距为0,保证在2.x的版本上运行没问题
		
		final EditText etPassword=(EditText) view.findViewById(R.id.et_password);
		final EditText etPasswordConfirm=(EditText) view.findViewById(R.id.et_password_confirm);
		
		Button btOk=(Button) view.findViewById(R.id.btn_ok);
		btOk.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				String password=etPassword.getText().toString();
				String passwordConfirm=etPasswordConfirm.getText().toString();
				
				if(!TextUtils.isEmpty(password)&&!TextUtils.isEmpty(passwordConfirm)){
					if(password.equals(passwordConfirm)){
						mpref.edit().putString("password", MD5Utils.encode(password)).commit();
						Toast.makeText(HomeActivity.this, "密码设置成功！", Toast.LENGTH_SHORT).show();
						dialog.dismiss();
						
					}else{
						Toast.makeText(HomeActivity.this, "两次密码不一致！", Toast.LENGTH_SHORT).show();
					}
					
				}else{
					Toast.makeText(HomeActivity.this, "密码不能为空！", Toast.LENGTH_SHORT).show();
				}
			}
		});
		
		Button btCancle=(Button) view.findViewById(R.id.btn_cancle);
		btCancle.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				//隐藏弹出框
				dialog.dismiss();
			}
		});
		
		dialog.show();
	}

重要代码：

AlertDialog.Builder builder=new AlertDialog.Builder(this);
final AlertDialog dialog=builder.create();
View view=View.inflate(this, R.layout.dialog_set_password, null);
//dialog.setView(view);
dialog.setView(view, 0, 0, 0, 0);//设置边距为0,保证在2.x的版本上运行没问题
