如何获取android安卓控件EditText中的内容

Answer 1

Android中Edit text控件的内容可以添加一个监听器，来获取内容放到别的控件上去，示例如下：

package nbe.sense7.vinci.edittext;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
public class EditTextDemoActivity extends Activity {
private EditText editText;
private TextView textView;

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

editText = (EditText)findViewById(R.id.input);
textView = (TextView)findViewById(R.id.output);

//设置EditText按键输入时的事件
editText.setOnKeyListener(new EditText.OnKeyListener(){
@Override
public boolean onKey(View arg0, int arg1, KeyEvent arg2) {
// TODO Auto-generated method stub
textView.setText(editText.getText());//获取edittext的内容
return false;
}
});
}
}

Answer 2

String address = ((EditText) v
.findViewById(R.id.et_lxdz)).getText()
.toString();

Answer 3

1. 设置EditText.setText(text);

2. 获取EditText.getText().toString();

3. EditText是编辑框，可以在string.xml中定义，在布局*.xml中@string/*来引用
