[英]My ImageView with an onClickListener does nothing when clicked
我在圖像上設置了一個onClickListener,以便在單擊圖像時,該值增加10。該值在屏幕上實時顯示。 但是,當我在模擬器中運行該應用程序並單擊該圖像時,無論單擊多少次或持續多長時間,都不會發生任何反應。
我相關的Java:
package com.bipbapapps.leagueclickerapp;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.widget.ImageView;
import android.widget.TextView;
public class MainClass extends Activity implements OnClickListener {
public float goldCount = 0.0f;
ImageView minionClick;
TextView textGoldCount;
String textTotal;
@Override
public void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Set fullscreen
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.mainlayout);
//Linking the variables
minionClick = (ImageView) findViewById(R.id.minioncentreid);
textGoldCount = (TextView) findViewById(R.id.textviewtop);
//String which will display at the top of the app
textTotal = goldCount + " Gold";
//Setting TextView to the String
textGoldCount.setText(textTotal);
//Setting onClickListener
minionClick.setClickable(true);
minionClick.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()){
case R.id.minioncentreid:
goldCount += 1.0;
break;
}
}
}
以及布局的XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainlayoutid"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/mainbackground"
android:weightSum="100"
>
<TextView
android:id="@+id/textviewtop"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="22"
android:textAlignment="center"
android:textColor="#FF6600"
android:textSize="25sp"
android:text="@string/app_name"
>
</TextView>
<ImageView
android:id="@+id/minioncentreid"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="50"
android:contentDescription="@+string/desc"
android:src="@drawable/minioncentrethree"
android:clickable="true"
/>
<TextView
android:id="@+id/textviewbottom"
android:layout_weight="28"
android:layout_height="0dip"
android:layout_width="wrap_content"
>
</TextView>
</LinearLayout>
有人知道如何解決此問題嗎?
您必須在onClick
方法中更新Textfield:
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.minioncentreid:
goldCount += 1.0;
textTotal = goldCount + " Gold";
textGoldCount.setText(textTotal);
break;
}
當前,您只是在更改變量。
