Android - basic control edit box EditText (6)

1.Use of EditText component

2.Specific content

How to use this component in layout file or Activity program? 

	<EditText 
	    android:id="@+id/myedit"
	    android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="请输入姓名:"
	    />
<EditText 
	    android:id="@+id/editname"
	    android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="请输入姓名:"
	    />
	<EditText 
	    android:id="@+id/editage"
	    android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:numeric="integer"—只能输入数字
	    />
	<EditText 
	    android:id="@+id/editpassword"
	    android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:password="true"—显示密文
	    />

Of course, we can also set the edit box to disable input.

<EditText 
	    android:id="@+id/editname"
	    android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="请输入姓名:"
        android:editable="false"—设置不可编辑
	    />

Of course, we can also set EditText in the Activity program.

public class EditTextActivity extends Activity {
	private EditText editText = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_edittext);
        this.editText = (EditText) super.findViewById(R.id.editname);
        this.editText.setText("中国您好");
        this.editText.setEnabled(false);//设置已有内容不可编辑
        this.editText.setTextSize(30.0f);//设置字体大小
    }
}

3. Summary

(1) The text editing box can realize the user data input function;

(2) The implementation of password relies on: "android:password="true"" attribute.
