在一个小部件设置ImageView的宽度和高度编程 [英] Set ImageView width and height programmatically on a widget

问题描述

我使用跌破code。使用远程视窗现在我想设置高度和宽度的ImageView运行时设置的一个小部件ImageView的图像。

 如果（appWidgetId！= AppWidgetManager.INVALID_APPWIDGET_ID）{
    AppWidgetManager appWidgetManager = AppWidgetManager.getInstance（WidgetActivity1_1.this）;
    RemoteViews remoteViews =新RemoteViews（WidgetActivity1_1.this.getPackageName（），R.layout.widget_layout1_1）;
    意图configIntent =新的意图（WidgetActivity1_1.this，UpdateWidgetService.class）;
    configIntent.putExtra（APPID，appWidgetId）;
    PendingIntent configPendingIntent = PendingIntent.getService（WidgetActivity1_1.this，appWidgetId，configIntent，0）;
    remoteViews.setImageViewResource（R.id.imgviewGrow，R.drawable.flower1）;
}
 

解决方案

您可以设置布局PARAMS progrematiclly是这样的：

  myImageView.setLayoutParams（新ViewGroup.LayoutParams（
ViewGroup.LayoutParams.WRAP_CONTENT，
ViewGroup.LayoutParams.WRAP_CONTENT））;
 

或者设置一些吧。

图片大小的操作有时可能非常棘手，它的建议首先得到 图像布局参数，可以改变它，设置回：

  android.view.ViewGroup.LayoutParams的LayoutParams = myImageView.getLayoutParams（）;
layoutParams.width = 30;
layoutParams.height = 30;
myImageView.setLayoutParams（的LayoutParams）;
 

如果你仍然有问题，来改变它的大小尽量把它的LinearLayout内，并使用布局PARAMS操作ImageView的大小：

  LinearLayout.LayoutParams的LayoutParams =新LinearLayout.LayoutParams（30，30）;
myImageView.setLayoutParams（的LayoutParams）;

I am using below code to set an image on a widget imageview using remoteview now i want to set height and width to imageview runtime.

if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
    AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(WidgetActivity1_1.this);
    RemoteViews remoteViews = new RemoteViews(WidgetActivity1_1.this.getPackageName(), R.layout.widget_layout1_1);
    Intent configIntent = new Intent(WidgetActivity1_1.this,UpdateWidgetService.class);
    configIntent.putExtra("Appid", appWidgetId);
    PendingIntent configPendingIntent = PendingIntent.getService(WidgetActivity1_1.this, appWidgetId, configIntent, 0);
    remoteViews.setImageViewResource(R.id.imgviewGrow, R.drawable.flower1);
}

解决方案

You can set the Layout Params progrematiclly this way:

myImageView.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));

or set a number instead.

Image size manipulation sometimes maybe tricky and it's recommended to first get image layout params, change it and set it back:

android.view.ViewGroup.LayoutParams layoutParams = myImageView.getLayoutParams();
layoutParams.width = 30;
layoutParams.height = 30;
myImageView.setLayoutParams(layoutParams);

and if you still have a problem to change it's size try to put it inside of a LinearLayout and manipulate the imageView size using the layout params:

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(30, 30);
myImageView.setLayoutParams(layoutParams);
