希望在<代码>Button上点击时通过<代码>TextView在屏幕上展示
我没有回答第二个问题,也许你可以阐述......但回答你的第一个问题。
String content = edtEditText.getText().toString(); //gets you the contents of edit text
tvTextView.setText(content); //displays it in a textview..
我刚刚开始帮助你们获得文本价值。 颁布这一法典
EditText edit = (EditText)findViewById(R.id.editext1);
TextView tview = (TextView)findViewById(R.id.textview1);
String result = edit.getText().toString();
tview.setText(result);
案文载于<代码>。 EditText 希望有助于你们。
EditText ein=(EditText)findViewById(R.id.edittext1);
TextView t=new TextView(this);
t.setText("Your Text is="+ein.getText());
setContentView(t);
bb.setOnClickListener(
new View.OnClickListener()
{
public void onClick(View view)
{
String s1=tt.getText().toString();
tv.setText(s1);
}
}
);
首先从编辑案文的角度来看待案文。
edittext.getText().toString()
以及 将已获得的文本放在一个插图中,即<代码> 数值/代码>。
value = edittext.getText().toString()
然后将<条码> 值/代码>作为<条码>>文本。
textview.setText(value)
yesButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
eiteText=(EditText)findViewById(R.id.nameET);
String result=eiteText.getText().toString();
Log.d("TAG",result);
}
});
从用户获取案文的最容易的方法:
EditText Variable1 = findViewById(R.id.enter_name);
String Variable2 = Variable1.getText().toString();
在“String.xml”中,你可以注意到你想要使用的任何优势或价值,这里有两个例子:
<string name="app_name">My Calculator App
</string>
<color name="color_menu_home">#ffcccccc</color>
用于布局:android:text="@string/app_name>
The advantage: you can use them as often you want, you only need to link them in your Layout-xml, and you can change the String-Content easily in the strings.xml, without searching in your source-code for the right position. Important for changing language, you only need to replace the strings.xml - file
在点击 but时使用以下代码:
String value = edittext.getText().toString().trim(); //get text from editText
textView.setText(value); //setText in a textview
希望对你们有益。
Try this->
EditText text = (EditText) findViewById(R.id.text_input);
Editable name = text.getText();
Editable is the return data type of getText() method it will handle both string and integer values
先从斜线案文中获取价值
String value = edttxt.getText().toString();
然后确定案文的价值 观点
txtview.setText(value);
Where edttxt refers to edit text field in XML file and txtview refers to textfield in XML file to show the value
