[英]Set ImageView width and height programmatically on a widget
我正在使用下面的代碼使用remoteview在小部件imageview上設置圖像現在我想將高度和寬度設置為imageview運行時。
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);
}
您可以通過以下方式設置布局參數:
myImageView.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
或者設置一個數字。
圖像大小操作有時可能很棘手,建議首先獲取圖像布局參數,更改它並將其設置回來:
android.view.ViewGroup.LayoutParams layoutParams = myImageView.getLayoutParams();
layoutParams.width = 30;
layoutParams.height = 30;
myImageView.setLayoutParams(layoutParams);
如果你還有問題需要改變它的大小,試着將它放在LinearLayout中並使用布局參數操作imageView大小:
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(30, 30);
myImageView.setLayoutParams(layoutParams);
更新:以下帖子可以幫助您滿足您的需求:
您可以嘗試使用這些線來設置imageview的寬度和高度
image_view.getLayoutParams().height = 20;
image_view.getLayoutParams().width = 100;
這應該工作!
image.getLayoutParams().height = 90;
