[英]i want to create a counter with a text view
我想創建一個帶有文本視圖的計數器,並希望每15次單擊即可更改文本視圖中的文本,這就是我為創建計數器而寫的內容........我有兩個文本視圖。 ...一個沒有 的點擊次數和另一個要顯示的文字,我想使用“ if”將計數器設置為0(計數器為tvx)並更改文本(tvx2) )以“再點擊15個”
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tips_2);
btn = (Button) findViewById(R.id.bt);
txv = (TextView) findViewById(R.id.tx);
txv2 = (TextView) findViewById(R.id.tx2);
btn.setOnClickListener(new View.OnClickListener()
{
public int mCounter;
public Integer tx;
@Override
public void onClick(View v) {
mCounter++;
txv.setText(Integer.toString(mCounter));
}
});
}
你可以這樣,使用ValueAnimator
public void animateText(Integer startValue, Integer endValue) {
setStartValue(startValue);
setEndValue(endValue);
ValueAnimator animator = ValueAnimator.ofInt(startValue, endValue);
animator.setInterpolator(getInterpolator());
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
String cleanString = animation.getAnimatedValue().toString().replaceAll("[,]", "");
BigDecimal parsed = new BigDecimal(cleanString);
String formatted = NumberFormat.getNumberInstance(Locale.US).format(parsed);
tv.setText(formatted);
}
});
animator.setEvaluator(new TypeEvaluator<Integer>() {
public Integer evaluate(float fraction, Integer startValue, Integer endValue) {
return Math.round(startValue + (endValue - startValue) * fraction);
}
});
animator.setDuration(getDuration());
animator.start();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tips_2);
btn = (Button) findViewById(R.id.bt);
txv = (TextView) findViewById(R.id.tx);
txv2 = (TextView) findViewById(R.id.tx2);
public int mCounter=0;
public Integer tx =15;
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mCounter++;
if(mCounter==tx){
txv.setText(Integer.toString(mCounter));
//reset the counter after 15 click
mCounter=0
}
}
}
);
}
}
您好,如果有幫助,請嘗試此
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tips_2);
btn = (Button) findViewById(R.id.bt);
txv = (TextView) findViewById(R.id.tx);
txv2 = (TextView) findViewById(R.id.tx2);
btn.setOnClickListener(new View.OnClickListener() {
public int mCounter=0;
//initialize mCounter with 0
public Integer tx;
@Override
public void onClick(View v) {
if(mCounter==15){
//check if mCounter equals 15
txv2.setText(Integer.toString("text to display after 15 click"));
//reset mCounter for another iteration
mCounter=0;
}
mCounter++;
//increment the mCounter
txv.setText(Integer.toString(mCounter));
}
});
}
我不太了解您想要什么,但是如果您希望每15次點擊增加一次計數器,只需在代碼中添加條件代碼,如下所示:
btn.setOnClickListener(new View.OnClickListener() {
public int mCounter;
public Integer tx;
@Override
public void onClick(View v) {
mCounter++;
if(mCounter == 15){
tx++;
txv.setText(String.valueOf(tx));
}
}
}
);
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tips_2);
btn = (Button) findViewById(R.id.bt);
txv = (TextView) findViewById(R.id.tx);
txv2 = (TextView) findViewById(R.id.tx2);
btn.setOnClickListener(new View.OnClickListener() {
public int mCounter;
public Integer tx;
public int mCounter2;
@Override
public void onClick(View v) {
mCounter++;
mCounter2++;
txv.setText(""+mCounter);
if(mCounter2==15){
txv2.setText(""+mCounter2);
mCounter2=0;
}
}
}
);
}
希望能為您服務
public class MainActivity extends AppCompatActivity {
private Button btn;
private TextView txv,txv2;
private int contador = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button) findViewById(R.id.bt);
txv = (TextView) findViewById(R.id.tx);
txv2 = (TextView) findViewById(R.id.tx2);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
++contador;
if(contador <= 15){
txv.setText(String.valueOf(contador));
}else{
txv2.setText("your text");
}
}
});
}
}
