點擊後重新載入圖片

Question

我需要幫助，我有表格3x3。點擊後如何在gridView中重新加載圖像？我想讓簡單的應用程序1好點擊= 1點。

public void losowanieTablicy() { 
int[] str_names = {0, 1, 2, 3, 4, 5, 6, 7, 8}; 
shuffle(str_names); 
shuffle(imgIds); 

for (int i = 0; i < imgIds.length; i++) { 
    ImageView img = (ImageView) findViewById(imgIds[i]); 
    final String str = "img_" + str_names[i]; // zakladajac ze str_names.length == imgIds.length 
    img.setImageDrawable(
     getResources().getDrawable(getResourceID(str, "mipmap", getApplicationContext())) 
    ); 
    } 
} 

public void shuffle(int[] a) { 
    int n = a.length; 
    for (int i = 0; i < n; i++) { 
     // between i and n-1 
     int r = i + (int)(Math.random() * (n - i)); 
     int tmp = a[i]; // swap 
     a[i] = a[r]; 
     a[r] = tmp; 
    } 
}

您可以添加一個onclick是這樣的：

final ImageView img = (ImageView) findViewById(imgIds[i]); 
img.setClickable(true); 
img.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View v) { 
    img.setImageDrawable(
    getResources().getDrawable(getResourceID(str, "mipmap", getApplicationContext())) 
); 
} 
});
