Android—获取view中的一个控件

<span style="font-size:14px;">
</span>

<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="400dip"
android:background="#FFFFFF" >

<com.insightcode.androidfont.FontTextTextView2
android:id="@+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="10dip"
android:gravity="center"
android:text="华南区"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#376092" />

<TextView
android:id="@+id/tv_cardview_dailyreport_all_achieve"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@id/textView1"
android:gravity="center"
android:paddingLeft="30dip"
android:text="1%"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#376092"
android:textSize="25dip" />

</RelativeLayout></span>

比如main.xml中有两个textview，我们要获取其中一个textview2

其实com.insightcode.androidfont.FontTextTextView2是我自己写一个类，继承TextTiew，为了区别和普通TextView，我设置微软雅黑字体，其实没要求就直接继承作为一个类就可以了

<span style="font-size:14px;">package com.insightcode.androidfont;
import com.insightcode.app.BusinessApplication;

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;
/**
* 文本为汉字，设置微软雅黑，日报的整体跟踪机构名称
*
*/
public class FontTextTextView2 extends TextView {
private Context mContext=null;
Typeface texttypeface=null;

public FontTextTextView2(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
if(mContext==null){
this.mContext = context;
}
if(texttypeface==null){
texttypeface = BusinessApplication.texttypeface;
}
this.setTypeface(texttypeface);
}

public FontTextTextView2(Context context, AttributeSet attrs) {
super(context, attrs);
if(mContext==null){
this.mContext = context;
}
if(texttypeface==null){
texttypeface = BusinessApplication.texttypeface;
}
this.setTypeface(texttypeface);
}

public FontTextTextView2(Context context) {
super(context);
if(mContext==null){
this.mContext = context;
}
if(texttypeface==null){
texttypeface = BusinessApplication.texttypeface;
}
this.setTypeface(texttypeface);
}
}</span>

然后在activity里面写如下函数

<span style="font-size:14px;"> /**
* 从当前view中查找TextView子控件
*
* @param group
* @return
*/
private FontTextTextView2 findTextView2(ViewGroup group) {
if (group != null) {
for (int i = 0, j = group.getChildCount(); i < j; i++) {
View child = group.getChildAt(i);
if (child instanceof TextView) {
return (FontTextTextView2) child;
} else if (child instanceof ViewGroup) {
FontTextTextView2 result = findTextView2((ViewGroup) child);
if (result != null)
return result;
}
}
}
return null;
}</span>

然后使用以上方法：

FontTextTextView2 ftt2 = findTextView2((ViewGroup)view);

ftt2就是要从xml中获取的控件，可以ftt2.getText()获取文本进行操作
