android - 开发自定义进度对话框android

Question

我正在开发一个多设备安卓应用程序。一切都很好，但有两件事。进度对话框和吐司在 android 中看起来非常小，但在 S2 中非常好。任何人都可以建议任何解决方法来增加吐司的大小和进度和义务。我已经在清单中提到了屏幕支持，但没有用。

Answer 1

您可以为任何类型的对话框或 toast 设置视图以具有自定义外观。下面提到的 Toast 示例同样适用于警报或进度对话框。

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate
(R.layout.custom_toast,(ViewGroup) findViewById(R.id.toast_layout_root));  
TextView text = (TextView) layout.findViewById(R.id.text); text.setText("This is a custom toast"); 
Toast toast = new Toast(getApplicationContext()); 
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG); 
toast.setView(layout); toast.show();

您可以创建自定义 toast，您可以在其中定义自己的布局。检查下面的代码。

XML 布局命名为“custom_toast.xml”</p>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toast_layout_root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:orientation="horizontal"
android:paddingLeft="10dp"
android:paddingRight="10dp" >

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#00AAE9"
android:orientation="horizontal"
android:paddingBottom="5dp"
android:paddingTop="5dp" >

<ImageView
android:id="@+id/toastImage"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginRight="10dp"
android:src="@drawable/ic_warning" />

<TextView
android:id="@+id/toastText"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:textColor="#FFFFFF"
android:textSize="7pt"
android:textStyle="italic" />
</LinearLayout>

</LinearLayout>

Toast.LENGTH_SHORT).show();

Button customToastButton = (Button) this.findViewById(R.id.customToastButton);
customToastButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {

//get the LayoutInflater and inflate the custom_toast layout
LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom_toast, (ViewGroup)
findViewById(R.id.toast_layout_root));

//get the TextView from the custom_toast layout
TextView text = (TextView) layout.findViewById(R.id.toastText);
text.setText("This is my custom toast");

//create the toast object, set display duration,
//set the view as layout that's inflated above and then call show()
Toast t = new Toast(getApplicationContext());
t.setDuration(Toast.LENGTH_LONG);
t.setView(layout);
t.show();
}
});

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

}
