设备旋转后未设置EditText [英] EditText not set after device rotation

问题描述

步骤如下: 1.运行应用程序->确定，将EditText设置为"hello" 2.手动清除文字 3.旋转设备

Steps are as follows: 1. Run app -> OK, EditText set to "hello" 2. Clear text manually 3. Rotate the device

我希望将EditText再次设置为"hello"，因为在旋转后会重新创建活动.但是，EditText为空.代码:

What I expect is that EditText is set again to "hello" because activity is recreated after rotation. However, EditText is empty. Code:

public class MainActivity extends AppCompatActivity {

EditText editText;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    editText = (EditText) findViewById(R.id.editText1);
    editText.setText("hello");
}
}

推荐答案

尝试将以下内容添加到xml布局的EditText规范中:

Try to add the following to your EditText specification in xml layout:

android:saveEnabled="false"
