绑定view

TextView tvColor;
           

绑定监听

@OnClick({R.id.activity_goods_address_left_layout, R.id.activity_goods_address_right_layout})
public void onClick(View view) {
    switch (view.getId()) {
        case R.id.activity_goods_address_left_layout:
            finish();
            break;
        case R.id.activity_goods_address_right_layout://添加
            Intent chooseStyle = new Intent(OrderAddressActivity.this, EditGoodsAddressActivity.class);
            startActivityForResult(chooseStyle, 401);
            break;
    }
}
           

@OnLongClick( R2.id.button1 ) //给 button1 设置一个长按事件 public boolean showToast2(){ Toast.makeText(this, "is a long click", Toast.LENGTH_SHORT).show(); return true ; }

@OnCheckedChanged({R.id.rg_home,R.id.rg_wealth,R.id.rg_account}) public void OnCheckedChangeListener(CompoundButton view, boolean ischanged ){ switch (view.getId()) { case R.id.rg_home: if (ischanged){//注意：这里一定要有这个判断，只有对应该id的按钮被点击了，ischanged状态发生改变，才会执行下面的内容 //这里写你的按钮变化状态的UI及相关逻辑 } break; case R.id.rg_wealth: if (ischanged) { //这里写你的按钮变化状态的UI及相关逻辑 } break; case R.id.rg_account: if (ischanged) { //这里写你的按钮变化状态的UI及相关逻辑 } break; default: break; } }

• 绑定Bitmap 资源：@BindBitmap( )

@BindView(R.id.mytestview)
ImageView mytestview;

@BindBitmap( R.mipmap.ic_launcher)//绑定Bitmap 资源
public Bitmap bitmap ;
           

mytestview.setImageBitmap(bitmap);
           

• 绑定string 字符串：@BindString()

@BindView(R.id.mytestte)
TextView mytestte;

@BindString(R.string.app_name)  //绑定资源文件中string字符串
        String str;
           

mytestte.setText(str);
           

• 绑定一个颜色值：@BindColor( )

@BindView(R.id.mytestte)
TextView mytestte;

@BindColor( R.color.colorAccent ) //具体色值在color文件中
        int black ;  //绑定一个颜色值
           

mytestte.setTextColor(black);
           

• 绑定string里面array数组：@BindArray()

<string-array name="city">
    <item>北京市</item>
    <item>天津市</item>
    <item>哈尔滨市</item>
    <item>大连市</item>
    <item>香港市</item>
</string-array>
           

@BindView(R.id.mytestte)
TextView mytestte;

@BindArray(R.array.city)  //绑定string里面array数组
        String [] citys ;
           

mytestte.setText(citys[2]);
