基於android中的按鈕單擊來填充bg顏色

我有一個可變的webColor，如果按下該按鈕，我想填充顏色代碼，因此下一頁（subHeader）上的imageView將與按鈕。基於android中的按鈕單擊來填充bg顏色

我得到這些錯誤

該應用是否崩潰，當您單擊按鈕或當你啓動應用程序？ –

我認爲你有＃c41e72更換"@string/webColor"在activity_content_activity XML像下面

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
      xmlns:tools="http://schemas.android.com/tools" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      tools:context="com.dredaydesigns.dredaycreativeportfolio.content_activity" 
      android:background="#0e6fa2"> 

<ImageView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/pageBanner" 
    android:layout_alignParentTop="true" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentStart="true" 
    android:background="@drawable/webactivityheader02"/> 

<ImageView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/subBanner" 
    android:layout_below="@+id/pageBanner" 
    android:layout_alignLeft="@+id/pageBanner" 
    android:layout_alignStart="@+id/pageBanner" 
    android:adjustViewBounds="false" 
    android:padding="8dp" 
    android:background="#c41e72"/>

，如果你想以編程方式設置它，寫以下代碼

MainActivity確實將您的顏色傳遞給下方方式

public class MainActivity extends ActionBarActivity { 
public String webColor= "webColor"; 
private Button mWebButton; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    mWebButton = (Button) findViewById(R.id.webButton); 

    mWebButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      // String webColor = mWebButton.getText().toString(); 
      Intent goToNext = new Intent(MainActivity.this,content_activity.class); 
      goToNext.putExtra(webColor,"#C41E72"); 
      startActivity(goToNext); 

     } 
    }); 


}}

和content_activity活動，

public class content_activity extends ActionBarActivity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(activity_content_activity); 
    String backgroundColor = intent.getExtras().getString("webColor"); 
    ImageView iv = (ImageView)findViewById(R.id.subBanner); 
    iv.setBackgroundColor(Color.parseColor(backgroundColor)); 


}}

oooh非常感謝你，我想我現在完全瞭解你，謝謝你！所以你必須用滿足字符串需求的值來啓動它，並且通過它來覆蓋它？ – dreday

我得到這個問題，因爲它無法找到我們在content_activity活動中引用的意圖.C：\ Users \ Andreas \ Downloads \ dredaycreativeportfolio \ app \ src \ main \ java \ com \ dredaydesigns \ dredaycreativeportfolio \ content_activity.java 錯誤：（17，34）錯誤：找不到符號變量意圖注意：某些輸入文件使用或覆蓋棄用的API。注意：使用-Xlint：deprecation重新編譯以獲取詳細信息。錯誤：執行任務'：app：compileDebugJava'失敗。 >編譯失敗;詳細信息請參閱編譯器錯誤輸出。 ' – dreday

oooh得到它的工作！添加了意向的前面！謝謝你幫助我！嗬！ – dreday
