Question

我有一个带有TextView的app小部件。

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
    android:id="@+id/widgetText"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:text="@string/defaultWidgetText"
    android:gravity="center"
    />
</FrameLayout>

我正在尝试通过调用

来更改文本对齐方式

views.setInt(R.id.widgetText, "setGravity", Gravity.CENTER);

来自RemoteView的

。但它使“问题加载小部件” 其他setInt（...）工作正常。

我不想创建另一个TextViews或Layouts。还有其他改变重力的方法吗？

Answer 1

我的解决方案是：

// Text Align
int gravity = widget_pf.getInt(Constants.Prefs.WIDGET_TEXT_ALIGN, 2);
if (gravity == 0)
    remoteViews.setInt(R.id.BalancesLinLayout, "setGravity", Gravity.LEFT);
else if (gravity == 1)
    remoteViews.setInt(R.id.BalancesLinLayout, "setGravity", Gravity.CENTER_HORIZONTAL);
else
    remoteViews.setInt(R.id.BalancesLinLayout, "setGravity", Gravity.RIGHT);

在widget_layout.xml中：

<LinearLayout
    android:id="@+id/BalancesLinLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical" >

        <TextView
            android:id="@+id/SampleText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ellipsize="marquee"
            android:singleLine="true"
            android:textColor="#FFFFFF"
            android:textSize="9sp" />

</LinearLayout>

到目前为止，这很简单。

所以......这是我的解决方案。小部件布局：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
    android:id="@+id/top_left_text"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:visibility="invisible"
    android:gravity="top|left"
    />
<TextView
    android:id="@+id/top_text"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:visibility="invisible"
    android:gravity="top|center_horizontal"
    />
<TextView
    android:id="@+id/top_right_text"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:visibility="invisible"
    android:gravity="top|right"
    />

<TextView
    android:id="@+id/left_text"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:visibility="invisible"
    android:gravity="left|center_vertical"
    />
<TextView
    android:id="@+id/center_text"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:visibility="visible"
    android:gravity="center"
    />
<TextView
    android:id="@+id/right_text"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:visibility="invisible"
    android:gravity="right|center_vertical"
    />

<TextView
    android:id="@+id/bottom_left_text"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:visibility="invisible"
    android:gravity="bottom|left"
    />
<TextView
    android:id="@+id/bottom_text"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:visibility="invisible"
    android:gravity="bottom|center_horizontal"
    />
<TextView
    android:id="@+id/bottom_right_text"  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:visibility="invisible"
    android:gravity="bottom|right"
    />
</FrameLayout>

onUpdate（...）方法：

widgetViews = new Hashtable<Integer, Integer>();

widgetViews.put(GRAVITY_TOP_LEFT, R.id.top_left_text);
widgetViews.put(GRAVITY_TOP, R.id.top_text);
widgetViews.put(GRAVITY_TOP_RIGHT, R.id.top_right_text);

widgetViews.put(GRAVITY_LEFT, R.id.left_text);
widgetViews.put(GRAVITY_CENTER, R.id.center_text);
widgetViews.put(GRAVITY_RIGHT, R.id.right_text);

widgetViews.put(GRAVITY_BOTTOM_LEFT, R.id.bottom_left_text);
widgetViews.put(GRAVITY_BOTTOM, R.id.bottom_text);
widgetViews.put(GRAVITY_BOTTOM_RIGHT, R.id.bottom_right_text);

Intent intent = new Intent(context, MinimalisticNotesWidgetActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
for(int id : widgetViews.values())
{
    views.setViewVisibility(id, View.INVISIBLE);
}

int id = widgetViews.get(textGravity);

views.setOnClickPendingIntent(id, pendingIntent);
views.setTextViewText(id, widgetText);
views.setFloat(id, "setTextSize", fontSize);
views.setInt(id, "setTextColor", textColor);
views.setViewVisibility(id, View.VISIBLE);

P.S。我知道，这是一种糟糕的编码风格，但互联网上的其他变体看起来是相同的=（

RemoteViews + TextView + setGravity
