获取编辑文本字段的值

我正在学习如何创建UI元素。我已经创建了一些EditText输入字段。在单击按钮时，我想捕获输入字段中的内容。

<EditText android:id="@+id/name" android:width="220px" />

那是我的领域。如何获取内容?

使用getText():

Button   mButton;
EditText mEdit;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mButton = (Button)findViewById(R.id.button);
    mEdit   = (EditText)findViewById(R.id.edittext);

    mButton.setOnClickListener(
        new View.OnClickListener()
        {
            public void onClick(View view)
            {
                Log.v("EditText", mEdit.getText().toString());
            }
        });
}

我猜你在调用EditText对象“mEdit”时必须使用这段代码:

.toString myActivity.this.mEdit.getText () ()

只需确保编译器知道要调用和使用哪个EditText。

我希望这个方法能奏效:

Integer.valueOf(mEdit.getText().toString());

我尝试了Integer.getInteger()方法而不是valueOf() -它没有工作。

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

  Button  rtn = (Button)findViewById(R.id.button);
  EditText edit_text   = (EditText)findViewById(R.id.edittext1);

    rtn .setOnClickListener(
        new View.OnClickListener()
        {
            public void onClick(View view)
            {
                Log.v("EditText value=", edit_text.getText().toString());
            }
        });
}

你可能还想看看黄油刀。它旨在通过使用注释来减少样板代码的数量。这里有一个简单的例子:

public class ExampleActivity extends ActionBarActivity {

    @InjectView(R.id.name)
    EditText nameEditText;

    @InjectView(R.id.email)
    EditText emailEditText;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_example);
        Butterknife.inject(this);
    }

    @OnClick(R.id.submit)
    public void onSubmit() {
         Editable name = nameEditText.getText();
         Editable email = emailEditText.getText();
    }
}

只需在build.gradle中添加以下依赖项:

compile 'com.jakewharton:butterknife:x.y.z'

作为替代，还有AndroidAnnotations。

从android中的EditText控件获取值。getext属性用于获取EditText的值:

EditText txtname = findViewById(R.id.name);
String name      =  txtname.getText().toString();

2016-01-03 07:06:17

一种更高级的方法是使用butterknife bindview。这消除了冗余代码。

在gradle的依赖项下;把这两行加起来。

compile('com.jakewharton:butterknife:8.5.1') {
        exclude module: 'support-compat'
    }
apt 'com.jakewharton:butterknife-compiler:8.5.1'

然后同步。在MainActivity中绑定编辑文本的示例

import butterknife.BindView;   
import butterknife.ButterKnife; 

public class MainActivity {

@BindView(R.id.name) EditTextView mName; 
...

   public void onCreate(Bundle savedInstanceState){
         ButterKnife.bind(this); 
         ...
   }

}

但是，当您感觉更舒服或开始处理大量数据时，这是一种替代方案。

试试这段代码

final EditText editText = findViewById(R.id.name); // your edittext id in xml
Button submit = findViewById(R.id.submit_button); // your button id in xml
submit.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) 
    {
        String string = editText.getText().toString();
        Toast.makeText(MainActivity.this, string, Toast.LENGTH_SHORT).show();
    }
});

最短和最简单

getText（editText）;

获取文本（按钮）;

getText（textView）;

一些解决方法

只要在你的BaseActivity中创建方法，如果你没有的话。

public class BaseActivity extends AppCompatActivity{
    public String getText(TextView tv) {
        return tv.getText().toString().trim();
    } 
}

并通过这个BaseActivity扩展你的所有活动。

public class YourActivity extends BaseActivity {
  @Override
  public void onCreate(Bundle savedInstanceState){
     getText(editText);
     getText(button);
     getText(textView);
  }
}

注意，EditText，按钮扩展TextView，所以我只创建getText(TextView电视)。

步骤1:创建名称为activity_main.xml的布局

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rl"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    tools:context=".MainActivity"
    android:background="#c6cabd"
    >
    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="17dp"
        android:textColor="#ff0e13"
        />
    <EditText
        android:id="@+id/et"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/tv"
        android:hint="Input your country"
        />
    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Get EditText Text"
        android:layout_below="@id/et"
        />
</RelativeLayout>

步骤2:创建类Main.class

public class Main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn = (Button) findViewById(R.id.btn);
        final TextView tv = (TextView) findViewById(R.id.tv);
        final EditText et = (EditText) findViewById(R.id.et);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String country = et.getText().toString();
                tv.setText("Your inputted country is : " + country);
            }
        });
 }
}

字符串值= YourEditText.getText().toString;

2020-06-05 12:21:41

如果你正在使用Kotlin，并且想让它通用，你可以使用扩展函数

扩展功能:

fun EditText.getTextString(): String {
    this.text.toString()
}

并直接从EditText中调用此方法

yourEditText.getTextString()
