1.计算出缓存的大小 显示在相应TextView上
/**
* 获取缓存大小
*/
String totalCacheSize = null;
try {
totalCacheSize = DataCleanManager.getTotalCacheSize(getActivity());
} catch (Exception e) {
e.printStackTrace();
}
TextView.setText(totalCacheSize);
2.点击相应TextView 弹出AlertLog
new AlertDialog.Builder(getActivity())
.setTitle("清除缓存")
.setMessage("是否确认清除缓存")
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//清除缓存的方法
DataCleanManager.clearAllCache(getActivity());
settingNumber.setText("0M");
Toast.makeText(getActivity(), "清除成功", Toast.LENGTH_LONG).show();
}
})
.setNegativeButton("取消", null)
.show();
//因为不仅只有MainActivity一个页面,总会有MainActivity被覆盖的时候,所以我们需要在MainActivity走onResume生命周期的时候,再次计算缓存大小。
@Override
public void onResume() {
super.onResume();
/**
* 获取缓存大小
*/
String totalCacheSize = null;
try {
totalCacheSize = DataCleanManager.getTotalCacheSize(getActivity());
} catch (Exception e) {
e.printStackTrace();
}
settingNumber.setText(totalCacheSize);
}
