令人困惑的标题，我知道，但不太清楚如何解释。 我会尽力而为。
我想要完成的是，当用户点击一个按钮时，一个字段中的文本被推送到firebase，然后下一个字段中的文本被推到下面。
这样的事情：
- ＆＃34; UID＆＃34; - ＆＃34; Scripttitle＆＃34; - ＆＃34;在scriptUrl＆＃34;
以下是我尝试使用的代码：
final EditText title = (EditText) rlLayout.findViewById(R.id.inputScriptTitle);
final EditText scripturl = (EditText) rlLayout.findViewById(R.id.inputScriptURL);
final Button button = (Button) rlLayout.findViewById(R.id.submitScriptButton);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child("scripttitle")
.setValue(title.getText().toString());
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child(title.getText().toString())
.setValue(scripturl);
我很害羞我只是做了一些非常基本的错误，但由于我是编程新手，我真的不知道那可能是什么。
logcat的错误是：

答案 0 :(得分：2)
您无法将视图设置为setValue。 scripturl是一个EditText。
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child(title.getText().toString())
.setValue(scripturl);
如果你这样使用，你就不会看到任何错误。
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.child(title.getText().toString())
.push()
.setValue(scripturl.getText().toString);
答案 1 :(得分：1)
替换以下代码
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child(title.getText().toString())
.setValue(scripturl);
带
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child(title.getText().toString())
.setValue(scripturl.getText().toString());
//因为您直接传递value in value方法替换并从编辑文本而不是对象传递数据
