これはStack Overflowでこの問題に関して投稿した最初の質問ではありません。マップフラグメントを現在の場所にズームするには、本当に助けが必要です。私は何も試していないとは思わないでください。私はたくさん試しました。Androidマップのフラグメントを現在の位置にズームできません
現在の場所ではなく別の場所にマップズームを試しても、現在の場所とにズームする必要があります。ここで何が起きているのかは考えられません。ここで

である私はドーム小さなミスをしたと思うし、それが別の場所にズームすると、それは私の国にも、近くではありません。
私のズーム位置の画像です。
誰かがどのように現在の場所に私の地図の断片をズームを教えてください。
何か助けていただければ幸いです。 :)

追加getMyLocation（）（）の編集が

何も起こりませんでした。 ： –
ああ、そのズームを取得して間違った場所に。右 – Gaurav
ええ、 'getMyLocation（）'も呼び出していないズームの部分が起こっている 'onMapReady（）'私は何をするのか分からない –
