独自メソッドの変数にアクセスできない RectF.intersects

androidのブロック崩しを作っています。ブロック１０段。

drawRectで描画したブロック（レンガ）とdrawCircleで描画したボールの衝突判定を行いたいです。
どちらもRectFを使って衝突判定します。

そこで、独自メソッドcollideWidth2のreturnで
RectF で作ったブロック配列の変数 rect_block, rect_block2（２段目）,rect_block3（３段目）・・・の値を使いたいのですが、スコープの範囲外なのでローカル変数を作れ、と言われます。

どうなおせばよいでしょうか。

追記

if (rectCheck.intersects(rect_ball, rect_block)) {
 return true;}

の rect_block部分にエラーが出ています。

forループの中のrect_block が never used  となっています。 

警告内容
・cannot resolve symbol rect_block 
collideWidth2のローカル変数 rect_blockを作れ

・RectF rect_block = null; としてrect_blockをforループの外に出せ

・rect_block を Blockクラスのフィールド変数にせよ

といった警告がでます。
