android - 根据在android中单击按钮填写背景颜色

标签 android

我有一个变量 webColor，如果按下该按钮，我想用颜色代码填充它，因此下一页(subHeader)上的 imageView 将与按钮颜色相同。

我遇到了这些错误

最佳答案

我认为您必须将 activity_content_activity xml 中的 "@string/webColor" 替换为 #c41e72，如下所示

 <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"/>

如果你想以编程方式设置它，写下面的代码

在 MainActivity 中通过以下方式传递颜色

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);

        }
    });


}}

在 content_activity Activity 中，

 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));


}}
