                SQLiteDatabase db;                      
                db = openOrCreateDatabase("Saftey.db", SQLiteDatabase.CREATE_IF_NECESSARY, null);
                db.setVersion(1);
                db.setLocale(Locale.getDefault());
                db.setLockingEnabled(true);
                ContentValues values = new ContentValues();
                values.put("hardBtn", "YES");

                /* String Lock="yes" ;
                 Bundle bundle = new Bundle();
                 bundle.putString("key", Lock);
                 Intent a = new Intent(Change_setting.this, ChildMode.class);
                 a.putExtras(bundle);
                 startActivity(a);*/
                super.onAttachedToWindow();
                this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
                isLock = true;
            }
            else
            {
                SQLiteDatabase db;                      
                db = openOrCreateDatabase("Saftey.db", SQLiteDatabase.CREATE_IF_NECESSARY, null);
                db.setVersion(1);
                db.setLocale(Locale.getDefault());
                db.setLockingEnabled(true);
                ContentValues values = new ContentValues();
                values.put("hardBtn", "NO");
                db.update("Setting", values, "id = ?", new String[] { "1" });
                //SharedPreferences pref = getSharedPreferences("pref",0);
                //SharedPreferences.Editor edit = pref.edit();
                //edit.putString("hard","no");
                //edit.commit();
                Toast.makeText(this, "Hard Button Un-Locked", Toast.LENGTH_LONG).show();
                isLock = false;
            }
    }

如何解决它？

我不想隐瞒点击，但只有当点击home键不起作用任何事情

I do not want to hide clickable but only when click on home button does not work any thing

推荐答案

您可以覆盖返回键 onBack pressed（），让它做什么，但你不能覆盖的home键，但你可以添加一些code到的onStop（）这是在home键preSS调用。

You can override the back key onBackPressed() and let it do nothing, but you can't override the home button but you can add some code to onStop() which is called upon home key press.

下面是一片code来控制回preSS

here is a piece of code to control backpress

@Override
public void onBackPressed()
{
    if ( checked1 ) // if checked do nothing , remeber tomove checked1 to be a class member
        return;
    super.onBackPressed();
}
