Android屏蔽返回键和home键

1.只屏蔽Home键，只需在Activity中重写onAttachedToWindow()方法

public static final int FLAG_HOMEKEY_DISPATCHED = 0x80000000;

@Overridepublic void onAttachedToWindow() {

//关键：在onAttachedToWindow中设置FLAG_HOMEKEY_DISPATCHED

this.getWindow().addFlags(FLAG_HOMEKEY_DISPATCHED);

super.onAttachedToWindow();}

2.只屏蔽返回键，只需在Activity中重写onBackPressed()方法

public void onBackPressed() {

//        super.onBackPressed();

//        屏蔽掉返回按键

}
