情况:
我按下应该启动这部分代码的按钮(正在进行中,尚未完成):
public void playerattack1(View view){
setContentView(R.layout.activity_fight_defense);
displaystats();
int attacktype = 1;
int dmgminimum = 10;
int dmgmaximum = 15;
Random rn = new Random();
int range = dmgmaximum - dmgminimum + 1;
int damage = rn.nextInt(range) + dmgminimum;
fight_p_attack(damage, attacktype);
sb.insert(0,"Attack!\n");
textView = (TextView) findViewById(R.id.teststring);
textView.setText(sb);
public void fight_p_attack(int damage, int attacktype){
setContentView(R.layout.activity_fight_defense);
int k9minimum = 1;
int k9maximum = 9;
Random rn = new Random();
int range = k9maximum - k9minimum + 1;
int k9 = rn.nextInt(range) + k9minimum;
switch (attacktype){
case 1:
switch (k9){
case 1: damage *= 2;
enemyhealth -= damage;
case 4: enemyhealth -= damage;
case 7: enemyhealth -= damage;
}
case 2:
switch (k9){
case 2: enemyhealth -= damage;
case 5: damage *= 2;
enemyhealth -= damage;
case 8: enemyhealth -= damage;
}
case 3:
switch (k9){
case 3: enemyhealth -= damage;
case 6: enemyhealth -= damage;
case 9: damage *= 2;
enemyhealth -= damage;
}
}
fight_update();
}
public void fight_update(){
textView = (TextView) findViewById(R.id.health);
textView.setText("Health: "+health+" ");
textView = (TextView) findViewById(R.id.mana);
textView.setText("Mana: "+mana+" ");
textView = (TextView) findViewById(R.id.gold);
textView.setText("Gold: "+gold+" ");
textView = (TextView) findViewById(R.id.respect);
textView.setText("Respect: "+respect);
textView = (TextView) findViewById(R.id.enemyhealthView);
textView.setText(enemyhealth);
}
我已经测试了一下,似乎如果我删除部分试图将 setText 设置为表格视图中的 TextView:
textView = (TextView) findViewById(R.id.enemyhealthView);
textView.setText(enemyhealth);
它不再崩溃(但显然桌子将是空的,这不是我想要的!
问题:我如何写到这样的表:
