使用自己的r文件进行反射以及遍历linearout包含的控件

我的布局里面有很多个textView 我总不能一个个重新设置 但是他们有 很多共性

 

public final class R { 
    public static final class attr { 
    } 
    public static final class drawable { 
        public static final int icon=0x7f020000; 
    } 
    public static final class id { 
        public static final int s1=0x7f050000; 
        public static final int s10=0x7f050009; 
        public static final int s11=0x7f05000a; 
        public static final int s12=0x7f05000b; 
        public static final int s13=0x7f05000c; 
        public static final int s14=0x7f05000d; 
        public static final int s15=0x7f05000e; 
        public static final int s16=0x7f05000f; 
        public static final int s2=0x7f050001; 
        public static final int s3=0x7f050002; 
        public static final int s4=0x7f050003; 
        public static final int s5=0x7f050004; 
        public static final int s6=0x7f050005; 
        public static final int s7=0x7f050006; 
        public static final int s8=0x7f050007; 
        public static final int s9=0x7f050008; 
    } 
    public static final class layout { 
        public static final int main=0x7f030000; 
        public static final int toast=0x7f030001; 
    } 
    public static final class string { 
        public static final int app_name=0x7f040000; 
        public static final int s2=0x7f040001; 
    } 
} 
上面的是我的r文件

import java.lang.reflect.Field; 
/* ... */ 
 
for (int i = 1; i < 16; i++) { 
    int id = R.id.class.getField("s" + i).getInt(0); 
    tv[i] = (TextView)findViewById(id); 
    tv[i].setTypeface(face); 
    tv[i].setClickable(true); 
    tv[i].setOnClickListener(clickListener); 
} 

当然如果你的布局如果只有textView组成 而没有其他的控件那就无需使用这个了

可以使用

public void onCreate(Bundle savedInstanceState) { 
            super.onCreate(savedInstanceState); 
 
            setContentView(R.layout.main); 
            LinearLayout ll = (LinearLayout) findViewById(R.id.LinearLayout01); 
            for (int i = 0; i < ll.getChildCount(); i++) { 
                ((TextView) ll.getChildAt(i)).setText("Text View " + i); 
            }
